Anyone run power estimation with vcd file before? I received warnings that nets are not covered by VCD file and an error,"Error: (read_vcd) Strip path can not be matched in the VCD file.
What I did are:
1) In testbech,
initial
begin
$dumpfile("top.vcd");
$dumpvar("0,top");
end
2) Run sim and obtain top.vcd
3) Read in gate netlist, spef file and vcd file in prime power.
Anything wrong with my steps? How should I verify those nets are in the vcd file?
Another question is how to clip the time so that we can get an accurate vcd for power calculation? Doing it manually after getting the vcd file or there is other ways to do so?
I noticed that the vcd file can easily become very large. How to handle and manage the vcd file? I read an article in solvenet, where we can split the vcd file. Anyone has tried before?
Thanks.
