timing analysis with generated clks
Let's say you have clk1 with freq1 and clk2 is generated from clk1 and it is freq1/2 (div2 of clk1). How do we time paths between two posedge flops with clk1 and clk2?
1. For setup, the timing between the two should be done at clk1 right?
2. And for hold, do we do our regular hold analysis on the same clk edge and clk freq does not matter?
