M1.5, M1.4, M1.3 LogiBLOX: Bus order reversed on LogiBLOX MUX macro symbols


Record #2798

Product Family: Software

Product Line: FPGA Implementation

Product Part: logiblox

Product Version: 1.5.

Problem Title:
M1.5, M1.4, M1.3 LogiBLOX: Bus order reversed on LogiBLOX MUX macro symbols


Problem Description:
Urgency: Hot

The LogiBlox mux macro symbol select lines are arranged
differently from those on X-BLOX symbols.



Solution 1:

M0 on the X-BLOX MUX symbol, and MA on the LogiBLOX MUX are
both selected by select 0, but while M0 is located on the
bottom of the X-BLOX symbol, MA is located at the TOP of the
LogiBLOX symbol:

X-BLOX		LogiBlox
m3  3		md   3
m2  2		mc   2
m1  1		mb   1
m0  0		ma   0


This should be noted when substituting X-BLOX modules
for the corresponding LogiBLOX counterpart.
