make spectre reuse ahdlcmi from previous design

[Svenn Bjerkem]

Hi,
I have a command line simulation with a spectremdl file that I run over
more spectre netlists. I see that when I set up a new simulation,
Spectre starts of compiling an ahdlcmi directory for each input scs
file. It does this only once for each file in each directory and then
reuses on later reruns. But it is quite annoying when I set up a clean
simulation. Then I have to wait for the moscaps (I think) to compile.
Is there an option to tell spectre to reuse an already compiled
ahdlcmi?

Hi Svenn,

I think what you want is as follows (c shell):

setenv CDS_AHDLCMI_DIR /simulation/design_a/veriloga_compiled

The above shell environment variable 'CDS_AHDLCMI_DIR' can be set to
change the location for the compiled veriloga model. For more info, you
can refer to spectre reference manual 'spectreref.pdf'.

Actually you may want to use:

CDS_AHDLCMI_SHIPDB_DIR

env var. This is covered in <mmsimDir>/doc/veriaref/veriaref.pdf - in Appendix
G.
