General Description: According to the XCR3032XL-5 data sheet numbers, a register transition propagates through the feedback path so quickly that it violates the hold time on the same and other flip-flops.
As a result, timing simulations in the software sometimes fail with hold-time violations for a valid design pattern with valid waveforms.
解决方案
The hold time specification will be decreased from 4ns to 3.5ns.
