CPLD XC9500/XL/XV: GSR is not used when using registers that are synchronously reset

説明

General Description:

When using a register with Synchronous reset, such as an FDR, the reset is not

mapped to the Global Reset Signal (GSR).

ソリューション

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.

Please refer to the Libraries guide for further information on these macros
