read_liberty warning #12

Closed tingjung closed 5 years ago

tingjung commented 5 years ago

Hi James, I got the warnings below after executing read_liberty command.

Warning: axis type normalized_voltage not supported. Warning: missing variable_2 attribute.

This is the lookup table which caused the warnings

lu_table_template (waveform_template_name) {
 variable_1: input_net_transition;
 variable_2: normalized_voltage;
 index_1 ("float…, float");
 index_2 ("float…, float");
 }

This variable is supported by Liberty format but may be unused here. Should I just ignore the warning messages like these? Thanks!

like it says, it is not supported. if you depend on functionality related to that attribute it won't work.
