2.1i 9500/xl Tsim- Timing model incorrect for negative edge triggered global clock signals

描述

Keywords: 9500, timing, negative, global clock

Urgency: Standard

General Description:
There is an error in the timing model such that the timing for
a negative edge triggered flip flop on the global clock net
uses the timing for a product-term clock net - thus appearing
slower than it really operates. This problem is not seen for
positive edge triggered registers.
