3.1i WebPACK XPLA CPLDFit - WARNING 5605: The 'TIMESPEC' statement/constraint in UCF is not supported.

Description

Keywords: 4.1i, 3.1i, XPLA, CoolRunner, timing, constraints

Urgency: Standard

General Description:
I have applied standard Xilinx timing constraints to a CoolRunner device, and it reports:

WARNING 5605: The 'TIMESPEC' statement/constraint in UCF/NCF is not supported in XCR.

Solution

XPLA3 first began supporting timing constraints in 4.1i. (There was no timing constraint support in the previous versions of software.)

There are no plans for the obsolete XPLA devices (XPLA1, XPLA2, 22V10) to support any timing constraints.
