Constraints:这个是 Vivado 中的约束文件,在 Xilinx 的官方文档中给出了constraints的描述以及三种主要的 constraints 的形式: Design constraintsdefine the requirements that must be met by the compilation flowin order for the design to be functional on the board. Not all constraints are used by all steps...
If this value is not met, then it must be fixed by the designer. To determine why there is a Max Skew Timing violation, first check the topology of the clock tree paths which are reported as failing paths. One of the clock paths will be referred to as the "Reference path" and the...
My design now (using project flow) fails timing, but no longer gives me a timing report. I get the following error message: [Route 35-39] The design did not meet timing requirements. Please run report_timing_summary for detailed reports. Resolution: ...
I'm a newer of vivado.In my project,the timing will go closure if I just only set the master clock constraints in xdc.For the same project,I append the "set input delay/set output delay" constraints on the IO ports of the second time,the timing will not ...
