"WebSo is the proper way to make vivado not relate the clocks in timing analysis is: set_clock_groups -asyncronous -group {CLK_P} -group {other_clk_p another_clk_p}. Will this make vivado not relate CLK_p to the other clocks other_clk_p another_clk_p? Also if it matters CLK_p is the name of the clk pin in the top level. " - Clock contraints xdc

2.6.5. Creating Clocks and Clock Constraints

WebSep 23, 2024 · The user writes the constraint below in their own xdc file. create_clock -name clk -period 200 [get_ports clk] This constraint would overwrite the Sysgen constraint resulting in the Sysgen module becoming unconstrained. The Sysgen module is instantiated as a submodule. The clocks coming from an MMCM are generated, and the … WebThis only creates the constraint for the clock to be used during timing analysis. It looks like ACLK is a top-level port and you need to tell the tools which package/pin the ACLK is coming from. The timing analysis constraint has no bearing on the actual runtime frequency of the oscillator connected to a pin.
