Problem Title:
XBLXGS 5.x: possible cause of error "Bad status 79500182 from
ddp_perform_check"



Problem Description:
An XBLOX design fails in XBLXGS when Fncsim8 is run with the -o option, but
works O.K. when fncsim8 is run with the -g option.  When the design is run
as fncsim8 <design> -o the fncsim8.log file lists the following:

   Making new bus_if09 symbol now...
   Copying graphics now...
   Copying instances now...
   Copying nets now...
   XBLXGS:  ERROR:  Bad status 79500182 from ddp_perform_check.

The problem is caused because the symbol ended up with obsolete pin names.
How this happened is still a mystery (Mar. 31, 1995).  The new Unified
symbol contains the pin names X and B(8:0), but not MENTOR_BUS and
XBLOX_BUS.


Solution 1:


Fncsim8 -o fails in XBLXGS on an XBLOX design with ddp_perform_check error

ERROR MESSAGE:	XBLXGS ERROR: Bad status 79500182 from ddp_perform_check.

LONG DESCRIPTION:

PROBLEM:

If you get an XBLXGS ddp_perform_check error, check if you have BUS_IFxx
symbols (where xx is a number) in your design.	If so, check the pin names.
If the pin names are MENTOR_BUS and XBLOX_BUS, do an "Update -> Instance"
on all BUS_IFXX symbols.  This will correct the problem.  If you do not
have BUS_IFxx symbols, then something else is wrong.
