综合时latch如何配置

同求，顶一个

I thought a lot of places would not allow latches in post-synthesis netlist.Just wondering if it is common practice to avoid latches

1. latch的时钟端create_clock
2. set_clock_transition, set_clock_uncertainty -setup , set_clock_uncertainty -hold
3. set_max_time_borrow
跟普通的clk没太大差别。
