OVERVIEW
This workshop will show you how to maximize your
productivity when using PrimeTime. You will learn
how to identify the opportunities to improve run
time, prepare for STA on your design and master
the skills required to investigate and gain familiarity
with the clocks and clock controlling signals
that will largely dictate your STA results.
This workshop will spend almost
an entire day in training you how to use the critical
report_timing command, so you can quickly identify
and debug almost any timing problem. You will
also learn how to set up useful procedures, variables
and aliases and find help quickly. At the end
of the workshop, you will know how to use a straightforward
and simple methodology to create and execute error-free
run scripts.
The workshop uses an SDF based flow; however the
material covered is essential for users performing
STA using parasitics as well.
Hands on labs follow each training module, allowing
the user to apply the skills learned in lecture.
OBJECTIVES
At the end of this workshop the student should
be able to:
* Interpret the essential details in a timing
report for setup and hold, recovery and removal,
and clock gating setup and hold
* Generate timing reports for specific paths and
with specific details
* Generate summary reports of the design violations
organized by clock, slack or by timing check
* Create, execute and debug a PrimeTime run script
* Identify opportunities to improve run time
* Create a saved session and subsequently restore
the saved session
* Identify the primary clock sources and the clock
controlling signals in an unfamiliar design
* Prepare for performing STA on a design and then
use this knowledge to respond to, focus and debug
your timing analysis
AUDIENCE PROFILE
Design or verification engineers who perform STA
using PrimeTime.
