Add tc_clk_or2 And Add Warning About tc_clk_mux2 Usage #27

Closed meggiman closed 1 year ago

meggiman commented 1 year ago

This PR adds a new generic clock gate cell (OR-gate) to the tc_clk.sv cell family. Furthermore, I added a warning about the limitations of the tc_clk_mux2 cell in common standard cell libraries. They are not glitch-free and must not be used for dynamic switching between two clocks without any additional precautionary steps.
