4.1i Virtex-E MAP - MAP does not convert RLOC_ORIGIN to a PCF LOC constraint for single-slice RPMs

描述

Keywords: RLOC_ORIGIN , LOC, macro, RPM, place

Urgency: Standard

General Description:
RLOC_ORIGIN constraints are sometimes dropped from single comp RPM macros instead of being converted to PCF LOCATE constraints.

解决方案

This problem will be fixed in the next major release after 4.1i.

Meanwhile, a work-around is to apply a LOC constraint to one of the symbols (FF, LUT) involved. The following is an example of UCF syntax to do this:

INST "register_x" LOC = CLB_R38C72.S0 ;
