From: Marcin Kościelnicki Date: Mon, 12 Aug 2019 15:57:43 +0000 (+0000) Subject: Add clock buffer insertion pass, improve iopadmap. X-Git-Tag: working-ls180~1097^2~17 X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=f4c62f33ac56bc5725c44ad822e75d2387f98061;p=yosys.git Add clock buffer insertion pass, improve iopadmap. A few new attributes are defined for use in cell libraries: - iopad_external_pin: marks PAD cell's external-facing pin. Pad insertion will be skipped for ports that are already connected to such a pin. - clkbuf_sink: marks an input pin as a clock pin, requesting clock buffer insertion. - clkbuf_driver: marks an output pin as a clock buffer output pin. Clock buffer insertion will be skipped for nets that are already driven by such a pin. All three are module attributes that should be set to a comma-separeted list of pin names. Clock buffer insertion itself works as follows: 1. All cell ports, starting from bottom up, can be marked as clock sinks (requesting clock buffer insertion) or as clock buffer outputs. 2. If a wire in a given module is driven by a cell port that is a clock buffer output, it is in turn also considered a clock buffer output. 3. If an input port in a non-top module is connected to a clock sink in a contained cell, it is also in turn considered a clock sink. 4. If a wire in a module is driven by a non-clock-buffer cell, and is also connected to a clock sink port in a contained cell, a clock buffer is inserted in this module. 5. For the top module, a clock buffer is also inserted on input ports connected to clock sinks, optionally with a special kind of input PAD (such as IBUFG for Xilinx). 6. Clock buffer insertion on a given wire is skipped if the clkbuf_inhibit attribute is set on it. --- diff --git a/examples/mimas2/run_yosys.ys b/examples/mimas2/run_yosys.ys index b3204b1ca..b48877811 100644 --- a/examples/mimas2/run_yosys.ys +++ b/examples/mimas2/run_yosys.ys @@ -1,4 +1,3 @@ read_verilog example.v -synth_xilinx -top example -family xc6s -iopadmap -bits -outpad OBUF I:O -inpad IBUF O:I +synth_xilinx -top example -family xc6s -ise write_edif -pvector bra example.edif diff --git a/passes/techmap/Makefile.inc b/passes/techmap/Makefile.inc index 56f05eca4..631a80aa5 100644 --- a/passes/techmap/Makefile.inc +++ b/passes/techmap/Makefile.inc @@ -16,6 +16,7 @@ endif ifneq ($(SMALL),1) OBJS += passes/techmap/iopadmap.o +OBJS += passes/techmap/clkbufmap.o OBJS += passes/techmap/hilomap.o OBJS += passes/techmap/extract.o OBJS += passes/techmap/extract_fa.o diff --git a/passes/techmap/clkbufmap.cc b/passes/techmap/clkbufmap.cc new file mode 100644 index 000000000..9ecc83071 --- /dev/null +++ b/passes/techmap/clkbufmap.cc @@ -0,0 +1,299 @@ +/* + * yosys -- Yosys Open SYnthesis Suite + * + * Copyright (C) 2012 Clifford Wolf + * + * Permission to use, copy, modify, and/or distribute this software for any + * purpose with or without fee is hereby granted, provided that the above + * copyright notice and this permission notice appear in all copies. + * + * THE SOFTWARE IS PROVIDED "AS IS" AND THE AUTHOR DISCLAIMS ALL WARRANTIES + * WITH REGARD TO THIS SOFTWARE INCLUDING ALL IMPLIED WARRANTIES OF + * MERCHANTABILITY AND FITNESS.
