Problem Title:
M1: Concept->MAP: WARNING:basnu - RAM symbol .. of type "ram32x1s" with
INIT value "0000": INITSTATE string shorter than width of the ROM



Problem Description:
Keywords: concept, map, ram32x1s, init

Urgency: standard

Reference: 17818

General Description:

If a Concept schematic uses a XC4000E(X) RAM32X1S module,
then the following warning may occur:

<output>
WARNING:basnu - RAM symbol "p1$i51" of type "ram32x1s" with INIT value "0000": I
NITSTATE string shorter than width of the ROM - padding with zeros.
</output>

This is due to the fact that the RAM32x1S has only 4 zeros
in its default INIT field--the correct number of zeros
should be 8.


Solution 1:

This MAP warning is harmless can be ignored.

If you want to make this warning go away, you can also change
the default INIT value to some 8-digit binary value (such as
eight zeros) to make this warning go away.
