CPLD - How do I invert the global set/reset (GSR) pin?

Description

General Description:

How do I invert the global set/reset (GSR) signal on a CPLD?

解决方案

You can invert the GSR signal by connecting an inverter between the BUFGSR output and the asynchronous set/reset pins of the desired flip-flops.

NOTE: Do not include any other combinational logic between the BUFGSR and the asynchronous set/reset pins of flip-flops. Doing so causes the software to not use the dedicated GSR net.
