spectreVerilog fails to run in IC5033 environment |
|
|
Hello,
We finally migrated to IC5033 over here but now face the problem that
our mixedsignal environment simply refuses to start (using the same
design with the same state as used previously in our IC446 environment.
There is no error reported at all in the spectreverilog output window
("spectre.out" file) and I can't find anything alarming in the
respective simulation tree either. All is says after a while is:
"Error" Problem encountered while executing verilog".
I have been struggling with the same kind of problem in an environment
where we had cadence (5033) integrated with Agilent's ADS environment.
The exaxt same error was reported (this time in "pure" spectre mode).
In the end this proved to be an OS-patch issue: Inside the ADS install
tree there was a shared library module, which took precedence over the
normal OS shared libs, conflicting with our OS.
Does anybody out here happen to know whether we are confronting the
same sort of problem with spectreVerilog?
Any suggestion is welcome......
Thx,
Jan.

Hi,
For some reason, I can't remember what, in our environment we have
the LDV stream (verilog) always in front of the DFII stream (analog)
in our PATH variable.
....
/<...>/cds/lnx86/ldv50_qsr2/tools/bin
/<...>/cds/lnx86/ic5033_usr3/tools/bin
/<...>/cds/lnx86/ic5033_usr3/tools/dfII/bin
....
Also we have an append to the LD_LIBRARY_PATH variable
for the LDV stream (verilog).
( Be aware this is TCL, not shell syntax)
setenv LDVHOME /<...>/cds/lnx86/ldv50_qsr2
append-path PATH $env(LDVHOME)/tools/bin
append-path LD_LIBRARY_PATH $env(LDVHOME)/tools/lib
Hope this helps,
Bernd

Hello,
The problem is solved over here. It had nothing to do with shared libs but
everything with a combination of factors:
- The used LDV version
- In combination with a configuration error in the testbench
The newer LDV version could not handle this config error. Advancing to the
latest LDV version we got installed (LDV51) did solve the problem (but still
a huge performance degradation caused by this misconfiguration).
I'm still puzzled why "LDV34" was able to handle this problem however.
Anyway: Thx for the feedback.
Rgds,
