ID:332189 derive_pll_clocks was called multiple times with different options. Repeated calls to derive_pll_clocks do not modify existing clocks.
CAUSE: There were multiple calls to derive_pll_clocks
with different options. Only an initial call to derive_pll_clocks
creates clocks. All subsequent calls are ignored. If any derived clocks are removed between calls to derive_pll_clocks
, the next call to derive_pll_clocks
will constrain those clocks with the new options.
ACTION: For best results, use only one call to derive_pll_clocks
in your Synopsys Design Constraints File (.sdc). If you changed the options to derive_pll_clocks
in your .sdc using the TimeQuest Timing Analyzer GUI, you must call reset_design
before re-reading the .sdc.
