Product Line:  FPGA Implementation

Problem Title:
LOGIBLOX:  Legal ranges reported by LogiBLOX for base 2 and base 4
numbers are incorrect.



Problem Description:
Legal ranges flagged by LogiBLOX DRC for base 2 and base 4
values of 2-bit wide buswidth for LogiBLOX CONSTANT,
COMPARATOR and	COUNTER modules are incorrectly specified.
An extra "0" is prefixed to the range values.

For base 2 numbers, the legal range of values is specified as
"-2#010# to 2#011#" (should be -2#10# to 2#11#), and for base
4 numbers, the legal range is specified as -4#02# to
4#03# (should be -4#2# to 4#3#).



Solution 1:


This is a known problem which could not be fixed in the M1.5
timeframe.  The extra "0" can be ignored.
