M1.5i LOGIBLOX: XC9500 Up/Down counters with bit widths greater than or equal to 9 bits do not count correctly.


Record #5466

Product Family: Software

Product Line: FPGA Implementation

Product Part: logiblox

Product Version: 1.5i

Problem Title:

M1.5i LOGIBLOX:	XC9500 Up/Down counters with bit widths greater than or equal to 9 bits do
not count correctly.



Problem Description:
Urgency : hot

General description :

LogiBLOX XC9500 Up/Down counters produced for the 9500 architecture do not count correctly. The incorrect count sequence is observed both in simulation and in the implemented module.


Solution 1:

This problem has been fixed in the 2.1i release.

If this is not available, the 8-bit Up/Down counter works correctly, so as a
workaround you can cascade counters of 8 bits or less together to create
larger counters.
