Verilator

Look at the error message - you should be able to see what's wrong (hint - look at the list of supported switches in the manual):

"Invalid Option: --top-moule"

THanks. But this is the real error

%Error: verilator: No Input Verilog file specified on command line, see verilator --help for more information %Error: Command Failed /usr/local/bin/verilator_bin -sc -O0 --language 1364-2005 -DHAS_DEBUG '-DTEST_FILE=../pacoblazeFiles/test/adc_ctrl.rmh' '-DTEST_CYCLES=2000' '-DTEST_IRQ=120' -DUSE_ONEHOT_ENCODING -DPACOBLAZE3 -I../pacoblazeFiles/pacoblaze -y ../pacoblazeFiles/pacoblaze --top-module pacoblazeSM_4XCPU_tb.v 

You don't have a filename on the command line, as it says! (Or if you believe it is, you're not giving enough information.) I appreciate your giving a new tool a try, but please try to spend a bit more time debugging yourself and describing the issue before posting.

Dear Sir/Mrs. The command we gave is: verilator_bin -sc -O0 --language 1364-2005 -DHAS_DEBUG '-DTEST_FILE=../pacoblazeFiles/test/adc_ctrl.rmh' '-DTEST_CYCLES=2000' '-DTEST_IRQ=120' -DUSE_ONEHOT_ENCODING -DPACOBLAZE3 -I../pacoblazeFiles/pacoblaze -y ../pacoblazeFiles/pacoblaze --top-module pacoblazeSM_4XCPU_tb.v

The --top-module and the filename is at the end of the command line. We get an error message.

Best ergards, Yehuda

No, it's not. you have "--top-module pacoblazeSM_4XCPU_tb.v", that is the option to specify the top module name, it isn't a filename.
