In using HSIM ( or NanoSIM), HSIMVCD2VEC command converts VCD file to Stimulus Input signal easily. Analog & Digital Block were easily simulated by this way.

question : I written SIG (signal information file) like this


#format %[#]
#scope tc_top
#in RESETB


and I extracted VCD file from verilog.

But I get an error log file like this.

Compiling "RGB_to_SD.sig" (signal info)
Compiling "RGB_to_SD.vcd" (VCD)
ERROR:No signals found in vcd file. This could be because of an error in the VCD file or, the scope was not specified using the signal info file

Error: cannot open file "hsim_vcd2vec.vec"


How to solve this problem?

thanks
