Altera Quartus II TimeQuest Timing Analyzer User Manual

About this manual

The Quartus II TimeQuest Timing Analyzer is a powerful ASIC-style timing analysis tool that validates the timing performance of all logic in a design. It uses an industry-standard constraint, analysis, and reporting methodology to verify timing paths.

Frequently asked questions

What is the default frequency assigned to clocks that have not been constrained?

The software assigns a default frequency of 1 GHz for unconstrained clocks.

What does negative slack indicate in the timing reports?

Negative slack indicates a timing violation along the design's timing paths.
