Why do we need DC if we can only use PT for synthesis?

[aifi]

hi all...

why we need DC if we can only use PT for synthesis?

 

[research235]

what is primetime used for

hello aify

Using DC r PT depends on wat exatly u will be working on .... for STA PT is best .

design compiler vs primetime

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.

primetime timing between cdc

I had heard tat PT is for timing verification and DC for synthesis.
formality for formal verification

difference timing dc prime time

hello every one

well according to me .. DC is the only one which can perform the syntheis. and PT can only do timing analysis ..

please let me know if I am wrong

[rsrinivas]

why primetime

yes only DC from those mentioned by aifi
other tools like leonardo spectrum is also popular

 

[research235]

timing engine, dc pt

ohh yeah ,,

This leonardo spectrum .. is it widely used .. ?

timing differences between pt and dc reports

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.

 

[asic_bh]

synopsys design compiler complete timing analysis

DC is synthesis and can do timing analysis also, PT cannot synthesis but PT is good for timing analysis. and PT should be used for STA sign off

 

[sarath51]

what is bc_wc

DC is indusrtey standard tool for synthesis and PT is for Signoff

Hi all,

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.

prime time and dc difference

DC is a widely used synthesis tool for ASIC, and it can do some simple timing analysis; PT is a very effective STA tool.

 

[zhangpengyu]

static timing analysis bc_wc

PT is to do STA,not for synthesis

dc prime time

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.

what does STA stand for?

 

[aifi]

synopsys dc vs pt

STA stand for static timing analysis

synopsys design compiler leonardo

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!!

DC vs PrimeTime

nice discussion on DC and PT

I am interested to knw algorithms !! what are the algorithms used in PT for STA ?

thanks
Shiv

Re: DC vs PrimeTime

DC is only for synthesis

PT is for STA(Static Timing analysis)

In PT we will get the input as Synthesis netlist, libraries, Parasitic data information, and SDF
