XC4000E: MEMGEN always uses the part 4005EPG156 for Synchronous Rams.


Problem Description:
Keywords: MEMGEN, XC4000E, synchronous RAM


Urgency: Standard

Description

MEMGEN will always use the part 4005EPG156 for Sync_Rams,
even if you specify a part on the command line with the
"parttype=4008EPC84" option, or if you specify the
part in the memory definition file (.mem).


Solution 1:

There shouldn't be a problem with this, because you will always
be instantiating this component (XNF file) in another higher
level module.  This higher level module will also need a part
type specified, and it will over-ride all lower level modules
part-types.

If you are still concerned you could hand edit the XNF file to
correct the PART record, but this shouldn't be necessary, and
is not recommended.
