Interval Timer creates an incorrect "assign counter_load_value" - Interval Timer creates an incorrect "assign counter_load_value" Description Due to a problem in the Quartus® II software version 13.1, Interval Timer will create an incorrect “assign counter_load_value” for clock periods more than 2^32 with counter size set to 64. For example: For clock period of 2^33, the generated incorrect assignment is as following: "assign counter_load_value = {1\'h2, 32\'hFFFFFFFF};" The correct assignment should be: "assign counter_load_value = {1\'h1, 32\'hFFFFFFFF};" Resolution A patch is available to fix this problem for the Quartus® II software version 13.1.4.
