如题哈
The clock tree sinks are the synchronous points of a clock tree.astro clock tree synthesis identifies the following pins as clock tree sinks.
.sequential cells'clock port with trigger edge information
.user-defined synchronous pins with tha ataDefineSyncPin or ataDefineSyncPort command
就是ending points
可以理解为 路径的endpoint
再直白些 就是flops
学习了。
end point 不一定是触发器吧?
end point 不一定是触发器吧?
是不是这样啊:
1),以寄存器作为end_point的叫做sink_pin。
2),以IP或组合逻辑作为end_point的叫做exclude_pin。啊?
触发器的时钟端是sink,data端是endpoint
