Hi

I have Verilog top mixed design. I want to dump "VHDL variables" in
the fsdb file (debussy).
Can any one suggest me, how to do this?
Note: $fsdbdumpvars is for pure verilog desings, right?

Thanks

Karthik,
Look at Debussy's documentation for xact details. Here is what
I found via a quick google search:

http://support.aldec.com/KnowledgeBase/Article.aspx?aid=000344

FSDB_DUMP: process
begin
fsdbDumpfile("simdata.fsdb");
fsdbDumpvars(0, "");
wait;
end process;

AFAIK, any "$" call is PLI, hence works in Verilog, some tools might
extend it to mixed designs - for instance $vcdpluson in VCS-MX works
for both VHDL & Verilog.

A good reference (via google) is:
http://www2.cic.org.tw/training/train_download/debussy0407.pdf

I got the following:

Approach 1 : fsdbDumpVariable FLI
Dump to FSDB file directly
Need to specify the variables separately
The naming rules of variables are different between
different simulators (ModelSim and NC-VHDL)
Ex: fsdbDumpVariable /system/line__85/flag
