Problem Title:
CPLD XC9500/XL/XV: GSR is not used when using registers that are synchronously reset
Problem Description:
Urgency: Standard
General Description:
When using a register with Synchronous reset, such as an FDR, the reset is not
mapped to the Global Reset Signal (GSR).
Solution 1:
The only way to emulate a synchronous reset with the XC9500 family register is to
gate the reset signal with the D input signal. Hence this is created via Product
Terms and the reset signal cannot utilize the GSR.
