首先说一下我的流程,先对整个工程start compilation,然后点击timequest timing analzise创建sdc文件,然后点击create timing netlist,然后写sdc文件,我只写了一句话creat_clock -name sync_clk -period 10.000 -waveform {2.000 8.000} [get_ports clk]然后开始分析错误,Critical Warning: Found minimum pulse width or period violations. See Report Minimum Pulse Width for details.
Critical Warning: Found minimum pulse width or period violations. See Report Minimum Pulse Width for details.

("eval" body line 1)
invoked from within
