XBLXGS 5.x: possible cause of error "Bad status 79500182 from ddp_perform_check"
Description
Keywords: XBLOX, error, bad status, ddp
Urgency: Standard
General 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
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.
