Hello everyone,
I have a design with a few generated clock and some data paths between the different clock groups. When I try to report the timing between two clock groups with
So my question is what exactly this apostrophe means, because apparently this has something to do with the behaviour of my report.
Best Regards
I have a design with a few generated clock and some data paths between the different clock groups. When I try to report the timing between two clock groups with
I do not get some existing paths, no matter how many max_path and nworst I set. On the other hand, when I report the timing directly from the cells I am intersed inreport_timing -from Clk2 -to Clk1
I see the path, but then the report shows me, that the launching cell is being clocked by a clock, called Clk2' (with an apostrophe after it) :report_timing -from I2/* -to Clk1
Startpoint: I2/Z_reg[7]
(rising edge-triggered flip-flop clocked by Clk2')
So my question is what exactly this apostrophe means, because apparently this has something to do with the behaviour of my report.
Best Regards
