+Change Log:
+
+DRAMPower v4.0 - * DRAMPower can now be compiled as a library. This enables a user
+ to access the tool through an API and log commands and their
+ corresponding time stamps, removing the need to store large
+ command traces on disk. In addition, cycle counting variables
+ have been changed to int64 to support longer simulations.
+ The library can be compiled without Xerces to remove an optional
+ dependency and reduce the size of the binary.
+ * Improved robustness. The latest build is automatically checked
+ out on a test server, compiled, and tested to verify that the
+ output matches an expected reference. The code is also compiled
+ with a large number of warning flags enabled and treats all
+ warnings as errors.
+ * Bug fix: Fixed bug in io/termination energy calculation.
+ * Bug fix: Fixed bug in calculation of auto precharge cycle.
+
+DRAMPower v3.1 - * Added IO and Termination Power measures from Micron's DRAM Power
+ Calculator, for all supported DRAM generations. In the case of
+ Wide IO DRAMs, these measures are already included in the provided
+ current specifications. This feature enables support for multi-rank
+ DRAM DIMMs (DDR2/3/4) and stacking of multiple Wide IO DRAM dies
+ (equivalent to ranks). To indicate use of multi-rank DRAMs or
+ multiple Wide IO DRAM dies/layers, the 'nbrOfRanks' parameter in
+ the memory specification XMLs can be employed. Note: The DRAM
+ command scheduler does not support multi-rank/multi-die DRAMs yet.
+ Only the power estimation component of DRAMPower has been updated
+ to support them. The current measures for dual-rank DRAMs only
+ reflect those for the active rank and not the idle rank. The
+ default state of the idle rank is assumed to be the same as the
+ current memory state, for background power estimation. Hence,
+ rank information in the command trace is not required.
+ * Added warning messages: New warning messages are provided, to
+ identify if the memory or bank state is inconsistent in the
+ user-defined traces. Towards this, a state check is performed on
+ every memory command issued.
+ * Improved run-time options: Users can now point directly to the
+ memory specification XML, instead of just the memory ID. Also,
+ users can optionally include IO and termination power estimates
+ (for both single and dual rank DRAMs) using '-r' flag in the
+ command line options.
+ * Bug fixes: (1) Refresh handler in the DRAM Command Scheduler was
+ kept ON in the Self-Refresh mode, when it can be turned OFF. This
+ bug has now been fixed. (2) Precharge All (PREA) always considered
+ precharging of all banks. It has now been modified to consider
+ precharging of the open/active banks alone.
+
+DRAMPower v3.0 - * Added support for LPDDR3 and DDR4 memories, besides the already
+ supported DDR2/DDR3, LPDDR/LPDDR2 and WIDE IO DRAM memories.
+ * Added DRAM Command Scheduler: To support users of DRAMPower
+ without access to DRAM controllers, we have added a simple DRAM
+ command scheduler that dynamically schedules DRAM commands as if
+ it were a memory controller. The scheduler assumes closed-page
+ policy, employs ASAP scheduling for DRAM commands (i.e. schedules
+ commands as soon as timing constraints are met), performs FCFS
+ scheduling on DRAM transactions and supports all the different
+ DRAM generations supported by the power model. The generated DRAM
+ command schedule is also analyzable for real-time applications.
+ Users can also select speculative usage of power-down or
+ self-refresh modes (if needed) for idle periods between
+ transactions. It should be noted that using this command scheduler
+ is optional and it can be (de-)selected during run-time and users
+ can switch back to the previously used DRAM command interface as
+ in the earlier versions.
+ * Improved run-time options: Users can specify the memory and the
+ trace file to be used by DRAMPower using command line options.
+ Additionally, if the DRAM command scheduler is being used, the
+ users can specify the degree of bank interleaving required, the
+ request size and power-down or self-refresh options. Also, for
+ DDR4 memories the bank group interleaving can be specified using
+ command line options.
+ * Bug fixes: (1) For command traces ending with a RD/WR/RDA/WRA
+ command, the tool did not consider completion of operations when
+ estimating the total trace energy. The missing cycles are now
+ taken into account.
+ (2) The IDD5 (REF current) specification for WIDE IO SDR memory
+ specifications only included 2 banks for refreshes instead of all
+ four. We would like to thank David Roberts from AMD for spotting
+ the issue in our DATE'13 article. These measures have been updated.
+ (3) When estimating precharge cycle for commands with
+ auto-precharge, (RDA/WRA), the command analysis tool employed the
+ last activation cycle in the entire DRAM instead of the particular
+ DRAM bank. This bug has been fixed in this release.
+
+DRAMPower v2.1 - * Added support for variation-aware power estimation, for a
+ selection of DDR3 memories manufactured using 50nm process
+ technology, based on the Monte-Carlo analysis presented in our
+ DAC'13 article.
+
+DRAMPower v2.0 - * Added support for LPDDR/LPDDR2 and WIDE IO DRAM memories, besides
+ the already supported DDR2/DDR3 memories.
+ * Faster analysis: The trace analysis component in DRAMPower v2.0
+ triggers the evaluation only during memory state transitions
+ (between active, precharged, active and precharged power-down,
+ refresh, self-refresh and power-up states) and not on every clock
+ cycle, as was the case till the last version. This optimization
+ speeds up the power simulations using DRAMPower by several times
+ over cycle-accurate analysis, resulting in fast power analysis,
+ without affecting the accuracy of the trace analysis or the
+ reported power and energy estimates.
+ * Verification effort: Our power model was verified by the
+ Microelectronic System Design group at TU Kaiserslautern using
+ circuit-level SPICE simulations of a DRAM cross-section. As a
+ result of this verification effort, a couple of power equations
+ have been modified for Refresh and Self-refresh operations. The
+ difference between the power and energy estimates reported by our
+ updated model and the equivalent circuit-level simulations is
+ < 2% for all memory operations of any granularity for all memories
+ supported by DRAMPower.
+
+DRAMPower v1.2 - * Supports different power-down and self-refresh modes in DDR2 and
+ DDR3 DRAM memories.
+ * Bug fix: Refresh power consumption equation in DRAMPower v1,
+ incorrectly subtracted IDD2n (precharge background current)
+ instead of IDD3n (active background current) from IDD5 (total
+ refresh current). This error has been rectified in this version.
+
+DRAMPower v1.0 - * Performs cycle-accurate memory command trace analysis and estimates
+ power and energy consumption numbers for the trace.
+ * It supports the basic memory operations like read, write, refresh,
+ activate and (auto) precharge in DDR2 and DDR3 memories.

+# DRAM Power Model (DRAMPower)
+[](https://travis-ci.org/ravenrd/DRAMPower)
+[](https://coveralls.io/r/ravenrd/DRAMPower?branch=master)
+## 0. Releases
+
+The last official release can be found here:
+https://github.com/ravenrd/DRAMPower/releases/tag/4.0
+
+The master branch of the repository should be regarded as the bleeding-edge version, which has all the latest features, but also all the latest bugs. Use at your own discretion.
+
+## 1. Installation
+
+Clone the repository, or download the zip file of the release you would like to use. The source code is available in src folder. src/cli/drampower.cc file gives the user interface, where the user can specify the memory to be employed and the command/transaction trace to be analyzed. To build, use:
+```bash
+make -j4
+```
+This command will download a set of trace files from https://github.com/Sv3n/DRAMPowerTraces which can be used as test input for the tool.
+
+## 2. Required Packages
+
+The tool was verified on Ubuntu 14.04 using:
+
+ * xerces-c (libxerces-c-dev) - v3.1 with Xerces development package
+ * gcc - v4.4.3
+
+## 3. Directory Structure
+ * src/: contains the source code of the DRAMPower tool that covers the power model, the command scheduler and the trace analysis tool.
+ * memspecs/ : contains the memory specification XMLs, which give the architectural, timing and current/voltage details for different DRAM memories.
+ * traces/ : contains 4 sample DRAM transaction traces and 1 sample command trace (after the installation / compilation)
+ * test/ : contains test script and reference output
+
+## 4. Trace Specification
+### Command Traces
+If the command-level interface is being used, a command trace can be logged in a file.
+An example is given in ```traces/commands.trace```
+
+The format it uses is: ```<timestamp>,<command>,<bank>```.
+For example, "500,ACT,2", where ACT is the command and 2 is the bank. Timestamp is in clock cycles (cc), the list of supported commands is
+mentioned in src/MemCommand.h and the bank is the target bank number. For non-bank-specific commands, bank can be set to 0. Rank need not be
+specified. The timing correctness of the trace is not verified by the tool and is assumed to be accurate. However, warning messages are provided, to identify if the memory or bank state is inconsistent in the trace. A sample command trace is provided in the traces/ folder.
+
+### Transaction Traces
+If the transaction-level interface is being used, a transaction trace can be logged.
+
+The format it uses is: ```<timestamp>,<transaction_type>,<address>```.
+For example, "35,READ,0x80028", where READ/WRITE can be the transaction type and the logical address (32-bits long and byte addressable) less than the maximum supported DRAM capacity of 4GB (32Gb).
+
+The tool uses a flexible and efficient memory map as follows: specified in HEX (0x). Timestamp is in clock cycles (cc) and maximum {row}-{bank}-{column}-{BI}-{BC}-{BGI}-{BL}
+Here, BI gives the degree of bank interleaving, BC gives the burst size (count), BGI gives the degree of bank group interleaving (for DDR4) and BL gives the burst length used by the device.
+Dual-Rank addressing is not yet supported. The BC and BL address bits are derived from the column address bits, whereas the BI and BGI bits are derived from the bank address bits.
+
+Four sample MediaBench application transaction traces have been provided. The MediaBench applications include: (1) EPIC Encoder, (2) JPEG Encoder, (3) H263 Encoder and (4) MPEG2 Encoder. These applications were independently executed on the SimpleScalar simulator with a 16KB L1 D-cache, 16KB L1 I-cache, 128KB L2 cache and 64-byte cache line configuration. We filtered out the L2 cache misses meant for the DRAM and logged them as transaction traces. These can be used with our command scheduler to generate equivalent command traces for any DRAM memory specified.
+
+## 5. Usage
+
+src/cli/drampower.cc is the main interface file, which accepts user inputs to specify memory to be employed and the command or transaction trace to be analyzed. If the transaction trace (DRAM command scheduler) is being used, the users can specify the degree of bank interleaving required, the request size and the use of power-down or self-refresh options. Also, for DDR4 memories bank group interleaving can be specified. Dual-rank DRAMs are not yet supported by the command scheduler. Note: Speculative use of power-down or self-refresh modes will increase the trace length due to the power-up latencies of these power-saving modes.
+
+To use DRAMPower at the command-level (command trace), after make, use the following:
+```bash
+./drampower -m <memory spec (ID)> -c <commands trace>
+```
+To use DRAMPower at the transaction-level (command scheduler), after make, use the
+following:
+```bash
+./drampower -m <memory spec (ID)> -t <transactions trace>
+```
+Additional options when using transactions trace [-t] include:
+ * [-i] ```<interleaving>```
+ * [-s] ```<request size>```
+ * [-g] ```<DDR4 bank group interleaving>```
+ * [-p] ```<0 - No Power-Down, 1 - Power-Down, 2 - Self-Refresh>```
+
+Also, when using either the commands trace or the transactions trace, the user can
+optionally include IO and Termination power estimates (obtained from Micron's DRAM
+Power Calculator). To enable the same, the '-r' flag can be employed in command line.
+
+If these options are not used, the default values assumed are:
+* interleaving = 1
+* request size = burst length * I/O width / 8 (in bytes) (from memory XMLs)
+* power saving = No power-down
+* bank group interleaving = 1
+* IO and termination = OFF (0)
+* Burst size (count) of 1
+
+## 6. Memory Specifications
+
+36 sample memory specifications are given in the XMLs targeting DDR2/DDR3/DDR4, LPDDR/LPDDR2/LPDDR3 and WIDE IO DRAM devices. The memory specifications are based on 1Gb DDR2, 1Gb & 2Gb DDR3, 2Gb LPDDR/LPDDR2 and 4Gb DDR4/LPDDR3 Micron datasheets and the 256Mb Wide IO SDR specifications are based on JEDEC timing specifications and circuit-level IDD measurements by TU Kaiserslautern, inplace of the as yet unavailable vendor datasheets. 4 of the memory specifications target dual-rank DDR3 DIMMs.
+
+Note: The timing specifications in the XMLs are in clock cycles (cc). The current specifications for Reading and Writing do not include the I/O consumption. They are computed and included seperately based on Micron Power Calculator. The IDD measures associated with different power supply sources of equal measure (VDD2, VDDCA and VDDQ) for LPDDR2, LPDDR3, DDR4 and WIDE IO memories have been added up together for simplicity, since it does not impact power computation accuracy. The current measures for dual-rank DIMMs reflect only the measures for the active rank. The default state of the idle rank is assumed to be the same as the complete memory state, for background power estimation. Accordingly, in all dual-rank memory specifications, IDD2P0 has been subtracted from the active currents and all background currents have been halved. They are also accounted for seperately by the power model. Stacking multiple Wide IO DRAM dies can also be captured by the nbrOfRanks parameter.
+
+## 7. Variation-aware Power And Energy Estimation
+
+15 of the included datasheets reflect the impact of process-variations on DRAM currents for a selection of DDR3 memories manufactured at 50nm process technology. These memories include:
+(1) MICRON_128MB_DDR3-1066_8bit - revision G
+(2) MICRON_128MB_DDR3-1066_16bit - revision G
+(3) MICRON_128MB_DDR3-1600_8bit - revision G
+(4) MICRON_256MB_DDR3-1066_8bit - revision D
+(5) MICRON_256MB_DDR3-1600_16bit - revision D
+
+The original vendor-provided datasheet current specifications are given in XMLs
+without suffixes such as _mu, _2s and _3s. XMLs including suffixes indicate that the
+current measures are either: (1) typical (mu), or (2) include +2 sigma variation (2s),
+or (3) include +3 sigma variation (3s). These measures are derived based on the
+Monte-Carlo analysis performed on our SPICE-based DRAM cross-section.
+
+To include these XMLs in your simulations, simply use them as the target memory.
+

+
+As can be noticed, the tool performs DRAM command scheduling and reports the number
+of activates, precharges, reads, writes, refreshes, power-downs and self-refreshes
+besides the number of clock cycles spent in the active and precharged states, in the
+power-down (fast/slow-exit) and self-refresh states and in the idle mode. It also
+reports the energy consumption of these components, besides the IO and Termination
+components in pJ (pico Joules) and the average power consumption of the trace in mW.
+It also reports the simulation start/end times and the total simulation time in seconds.
+
+## 9. DRAMPower Library
+
+The DRAMPower tool has an additional feature and can be used as a library.
+In order to use the library run "make lib", include src/libdrampower/LibDRAMPower.h in your project and
+link the file src/libdrampower.a with your project.
+An example for the usuage of the library can be found in the folder test/libdrampowertest/lib_test.cc
+
+## 10. Authors & Acknowledgment
+
+The tool is based on the DRAM power model developed jointly by the Computer Engineering Research Group at TU Delft and the Electronic Systems Group at TU Eindhoven and verified by the Microelectronic System Design Research Group at TU Kaiserslautern with equivalent circuit-level simulations. This tool has been developed by Karthik Chandrasekar with Yonghui Li under the supervision of Dr. Benny Akesson and Prof. Kees Goossens.
