Dear everyone
I am studying a file of timing lib and there are some questions need your help.
In the program as follows, what does the data in the index_1 & index_2 mean? Do they mean rising time or loading capacitance? Thanks very much!
delay_model : table_lookup;
/* 2. Define template of size 3 x 3*/
lu_table_template(constraint_template) {
variable_1 : constrained_pin_transition;
variable_2 : related_pin_transition;
index_1 ("0.0, 0.5, 1.5");
index_2 ("0.0, 2.0, 4.0");
}
. . .
