LogiBLOX - The legal ranges reported by LogiBLOX for base 2 and base 4 numbers are incorrect.

Description

Keywords: base 2, base 4, legal range

Urgency: Standard

General Description:
The 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

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