   5 ## Requirements
   6
   7  * Icarus Verilog (built from latest sources)
   8  * ECP5 instances models from a Lattice Diamond installation (just install Lattice Diamond)

  11
  12 ### simcrg
  13
  14 Simulates the CRG used in ECPIX5 gram tests and checks for a few assertions.
  15
  16 ```
  17 ./runsimcrg.sh
  18 ```
  19
  20 Produces `simcrg.fst` (compatbile with Gtkwave).
  21
  22 ### simsoc
  23
  24 Simulates a full SoC with a UART Wishbone master and a DDR3 model, and sends the init commands that libgram would send over serial.
  25
  26 ```
  27 ./runsimsoc.sh
  28 ```
  29
  30 Produces `simsoc.fst` (compatible with Gtkwave).
