最严重的脉冲宽度违例在报告中显示为最差脉冲宽度时序裕量 (WPWS)。 如需了解脉冲宽度违例的详情,请在 Vivado GUI 中打开脉冲宽度违例报告,方法是单击“报告 (Reports)”->“时序 (Timing)”->“脉冲宽度报告 (Report Pulse Width)”,或者也可使用以下 Tcl 命令打开此报告: report_pulse_width 最大偏差违例 ...
标题 63684 - 2014.4 Vivado UltraScale Timing - Min Pulse-width violation on SDR I/O register Description I have a min pulse-width violation on an SDR I/O register. What options do I have to get around this violation? Solution The SDR register in the UltraScale and UltraScale+ has a lo...
You can see that there is a negative slack for the Min period. This violation needs to be resolved to overcome the pulse width violation. In this example, the Required value of 2.155ns and the Actual value of 1.250ns show the corresponding values for check type (Min Period). The Slack c...
