Problem Title:
1.5i Map - run time error - pure virtual call
Problem Description:
Map fails with:
runtime error R6025 - pure virtual function call
This is a bug in the mapper, but it is exposed by a rather unusual circuit configuration. A flop (E
XECUTION_ENGINE_INTERNALS_WATCHDOG_TIMER_watchdog_timeout) has a constant 0 on its D input, so it re
duces to a constant 0. Its output signal (installed_led_1) drives an INV and then both the I and T
inputs of an OBUFT. Thus, the OBUFT sees a constant 1 on both of its inputs. This causes the mappe
r to crash.
Solution 1:
A fix for this problem is included in the 1.5i Service Pack 1. For details
