2.1i Design Manager: FPGA Multi-Pass Place and Route (MPPR) greyed out

Description

Keywords: Multi-Pass, Place, Route, M1.4, M1.3, M1.5, grey, MPPR

Urgency: Standard

General Description:

Trying to perform a multi-pass place and route (MPPR), however
the menu selection under the Design Menu is greyed out.

Solution

1

If you're using 2.1i Software:

You must have a Version OR Revision selected in order to
select the option of running a Multi-Pass Place and Route.
Having the project name highlighted will not give you access
to MPPR.

If you're using 1.5i Software or older:

You must have a Version selected in order to select the
option of running a Multi-Pass Place and Route. Having
the project name or revision highlighted will not give you
access to MPPR.

MPPR can only operate on Xilinx FPGA families: XC3000a, XC4000e,
XC4000ex, XC4000XL, XC5200 and Spartan. It cannot operate on
CPLD's: XC7000, XC9500. This may be another reason why the option
is greyed out.
