Hello,
How do I instruct simvision to force the creation of a vcd file?
I am trying to create tcl script to dump signals into a vcd file and then immediately post-process this very vcd.
These are the two lines I want to run in sequence from a ncsim tcl script :
simvision -submit "database export $my_signals -format vcd -name my_vcd.vcd"
file copy my_vcd.vcd ${my_dir}/myvcd.vcd
The problem that I am experiencing is that simvision seems to postpone the creation of the vcd file. Therefore, at the moment the second line is executed the vcd file is not yet available.
I get the following error:
ncsim> *E,TCLERR: error copying "driver.vcd": no such file or directory
However, if I run the two lines separately (i.e., not in a script) it works.So It seems that I have to force the creation of the vcd, but I don't know how.
I would appreciate your help.
Thanks!
