The timing analyzer tas reports its results in a file, named `perfmodule'. There are two kind of perfmodules: the `intermediate' (or `detailed") and the `general'. The first one has a htv extension and is obtained if the -t option is used. It contains gate delays between two signals. The second one has the ttv extension and contains all critical paths between two reference points. The perfmodule has several articles.
X direction name capacitance ;
The `terminal' direction can be:
L name ( cmd1 cmd2 ... ) ;
A latch may have several commands. All of them belong to the L article.
Precharged signals Precharged signals are reported on the P article.
P name ;
T type begin end ( (control (input_commutation output_commutation delay resistance slope))) ;
Each `transition' has one of the following type:
Each `commutation' has one of the following type:
If the end of path is a register, the `control' field indicates which signal controls the transition. And if the end of path is a terminal, in each transition, the output resistance and the output slope will be reported. This allows a hierarchical analysis. In the other case, only the delay appears in the transition line.
