signal on bel G



Problem Description:
Keywords:  map, x4kma, x4kmabel, 161:1.37

Urgency: standard

General Description:
Executing MAP may yield the following error message:

FATAL_ERROR:x4kma:x4kmabel.c:161:1.37 - Didn't find out signal on bel G of comp
I_036818/ram_spo<2><6>


Solution 1:

If the above error message is seen on a design that contains Dual Port RAM, and
the DPO pin is not hooked up, then MAP for version 1.2.11 may give this error. T
he solution is to either use the DPO pin or to substitute a Sync. RAM instead (w
hich does not have a DPO pin). If you are indeed using your DPO pin, then you sh
ould check to see if the logic it sources was trimmed.
