Subject: Problems Exporting From Synopsys dc_shell To EPIC PowerMill
I am using EPIC's PowerMill to estimate power usage for netlists which I
have created through Synopsys dc_shell. I would like to export the
pre-layout parasitic values being calculated for each net from Synopsys's
wire load models so that I can use them in the PowerMill run.
I haven't been able to find a direct way of doing this, however. The
closest "approved" method I've seen of getting the parasitic values out
from the dc_shell is using the "write_parasitics" command, which generates
an SPEF-format file. Unfortunately, the only format for a parasitics file
which PowerMill accepts is DSPF, which is apparently incompatible.
Is there an easy translation available for SPEF to DSPF, or is there a
freeware/shareware/commercial product available which can do this? (Or any
other solution to this problem?)
