Hi,
DC has a timing analysis engine and generates reports on setup, hold violations and slack analysis, but its not as accurate as PT. as far as synthesis goes, according to my knowledge, PT can't synthesize.
DC is for synthesis, and can do some simple timing analysis.
but only PT can be a final sign-off STA tool.
PS. they have different algorithm for STA inside themselve.
the DC contains the algorthems used in primetime but those r not much accurate as primetime.the DC is mainly ment for the timing optimisation ratherthan timing calculation.

Right.
DC and primetime are both from synopsys and it
contains the libraries of PT to support it. leonardo
spectrum is widely used but is not as popular as
synopsys DC.By the way the only tool synopsys
got recognition in the industry was from DC.
synopsys, Cadence , Magma & Mentor Graphics are some leading EDA tool companies .First of all thers' no single tool which does the whole flow except in the case of Magma. Each of these companies excel only in a particular area in Design flow. In analog side Cadence is the leader in the whole flow. While in digital side its a combination of all these companies.For doing synthesis synopsys has Design Compiler (commonly called DC). Mentor Graphics synthesis tool is Leonardo spectrum. Cadence synythesis tool is called Build Gates. Magma's well known for their physical design tool. In a synthesis tool there is an internal timing analysis engine which checks whether timing parameters are met or not. But It s not tht accurate. Hence for doing timing analysis a seperate tool is used.
Prime time from synopsys is the industry standard tool for doing it.
Dear sirs,
But I still don't know exactly the difference between DC & PT.
The PT STA is more accurate than DC. Can take a example?
From the PT refference maual, I know the PT is powerful than DC.
For example, PT can do chip variation analysis. DC seem not.
If I only use the basic function to do STA, for example only
setup/hold time check. Do they still have great difference??
Thanks for your anaswer!!
