General Description: The Virtex Multiplier core v1_0.1 released in C_IP2 has an option that allows the user to customize the core so that a Set input will override a Clear input when both are asserted at the same time. This option can also be specified in an .XCO file by setting the set_clear_priority parameter to "set_overrides_clear.
In the 1.0 version of the multiplier, this option does not work. The result is that Clear overrides Set regardless of what the user has specified.
There is no workaround to this problem at this time.
