Post synth simulation

[tsp6]

I am using wsl system. In the post synthesis simulation, when i try to use the Icarus Verilog simulator I got this error :

tsp@DESKTOP-S7PFFHU:~/Projects$ iverilog -o example.vvp example_synth.v example_tb.v yosys/gatemate/cells_sim.v yosys/gatemate/cells_sim.v: No such file or directory example_synth.v:17: error: Unknown module type: CC_LUT3 example_synth.v:23: error: Unknown module type: CC_BUFG example_synth.v:32: error: Unknown module type: CC_DFF example_synth.v:44: error: Unknown module type: CC_DFF example_synth.v:56: error: Unknown module type: CC_DFF example_synth.v:68: error: Unknown module type: CC_DFF example_synth.v:80: error: Unknown module type: CC_DFF example_synth.v:92: error: Unknown module type: CC_DFF example_synth.v:104: error: Unknown module type: CC_DFF example_synth.v:116: error: Unknown module type: CC_DFF example_synth.v:123: error: Unknown module type: CC_IBUF example_synth.v:127: error: Unknown module type: CC_OBUF example_synth.v:131: error: Unknown module type: CC_OBUF example_synth.v:135: error: Unknown module type: CC_OBUF example_synth.v:139: error: Unknown module type: CC_OBUF example_synth.v:143: error: Unknown module type: CC_OBUF example_synth.v:147: error: Unknown module type: CC_OBUF example_synth.v:151: error: Unknown module type: CC_OBUF example_synth.v:155: error: Unknown module type: CC_OBUF example_synth.v:159: error: Unknown module type: CC_IBUF 21 error(s) during elaboration. *** These modules were missing: CC_BUFG referenced 1 times.

This is the path of my files and yosys installation:

tsp@DESKTOP-S7PFFHU:~$ ls Projects cc-toolchain-linux ghdl ghdl-yosys-plugin yosys yosys.log tsp@DESKTOP-S7PFFHU:~$ cd Projects/ tsp@DESKTOP-S7PFFHU:~/Projects$ ls adder.v example.ccf example_synth.v python.ipynb yosys.log c++.cpp example.v example_tb.v synth_adder.v tsp@DESKTOP-S7PFFHU:~/Projects$

yosys/gatemate/cells_sim.v: No such file or directory

Your path to cells_sim.v isn't correct (I'm somewhat surprised Icarus doesn't just give up at that point, but hey ho).

I think you probably want ../yosys/techlibs/gatemate/cells_sim.v

It worked. thnanks

I also had an issue after generating vcd file. In order to view the vcd file, I have already installed the packages for GTK wave wavefor viewer. Then when I use this command:

tsp@DESKTOP-S7PFFHU:~/Projects$ vvp -N example.vvp VCD info: dumpfile example_tb.vcd opened for output. tsp@DESKTOP-S7PFFHU:~/Projects$ gtkwave example_tb.vcd Could not initialize GTK! Is DISPLAY env var/xhost set?

Usage: gtkwave [OPTION]... [DUMPFILE] [SAVEFILE] [RCFILE]

-n, --nocli=DIRPATH use file requester for dumpfile name -f, --dump=FILE specify dumpfile name -F, --fastload generate/use VCD recoder fastload files -o, --optimize optimize VCD to FST -a, --save=FILE specify savefile name -A, --autosavename assume savefile is suffix modified dumpfile name -r, --rcfile=FILE specify override .rcfile name -d, --defaultskip if missing .rcfile, do not use useful defaults -D, --dualid=WHICH specify multisession identifier -l, --logfile=FILE specify simulation logfile name for time values -s, --start=TIME specify start time for LXT2/VZT block skip -e, --end=TIME specify end time for LXT2/VZT block skip -t, --stems=FILE specify stems file for source code annotation -c, --cpu=NUMCPUS specify number of CPUs for parallelizable ops -N, --nowm disable window manager for most windows -M, --nomenus do not render menubar (for making applets) -S, --script=FILE specify Tcl command script file for execution -T, --tcl_init=FILE specify Tcl command script file to be loaded on startup -W, --wish enable Tcl command line on stdio -R, --repscript=FILE specify timer-driven Tcl command script file -P, --repperiod=VALUE specify repscript period in msec (default: 500) -X, --xid=XID specify XID of window for GtkPlug to connect to -1, --rpcid=RPCID specify RPCID of GConf session -2, --chdir=DIR specify new current working directory -3, --restore restore previous session -4, --rcvar specify single rc variable values individually -5, --sstexclude specify sst exclusion filter filename -I, --interactive interactive VCD mode (filename is shared mem ID) -C, --comphier use compressed hierarchy names (slower) -g, --giga use gigabyte mempacking when recoding (slower) -L, --legacy use legacy VCD mode rather than the VCD recoder -v, --vcd use stdin as a VCD dumpfile -O, --output=FILE specify filename for stdout/stderr redirect -z, --slider-zoom enable horizontal slider stretch zoom -V, --version display version banner then exit -h, --help display this help then exit -x, --exit exit after loading trace (for loader benchmarks)

VCD files and save files may be compressed with zip or gzip. GHW files may be compressed with gzip or bzip2. Other formats must remain uncompressed due to their non-linear access. Note that DUMPFILE is optional if the --dump or --nocli options are specified. SAVEFILE and RCFILE are always optional.

can I get any help for this

This looks like a GTKWave/WSL issue (probably you need an X server or similar set up but I'm not sure how the standard WSL approach is there). Not something related to Yosys at this point.
