do you use hspice or spectre

[devop]

maybe most of the designers use the hspice to do simulation ,it's becoming the "golden",why?
can you tell me some advantage of the spectre?

 

[wonbef]

speed, precision, ...

 

[flyinspace]

It seems Hspice is still the "golden" for traditional spice simulator, not Spectre.

I don't think so.
In a large schemes, about 100000 transistirs, spectre is much faster.
Besides, spice doesn't support mixed signal simulation.
If I'm wrong, correct me.

Spice is the primitive one...

 

[renwl]

the spectre has less convergence problem. so i use spectre.

 

[vinodjn]

spectre is much faster than spice, no doubt,
but i think licens cost of spectre is more than spice.

 

[jonashat]

Spectre is newer, supposedly more advanced, many features (specially in Spectre RF) and wayy more expensive...

I don't know the detailed cost of it. can somebody give some information?
if we use the spice for simulation, which tool for layout?

 

[jonashat]

the simulation tool doesn't have anything to do with the layout tool.

You are absolutely right.
The thing is that spectre licence couldn't be obtained without the whole cadence environment, so it will be much expensive than any spice-like simulator.

Hspice is more popular because of the convenience of PC version.

 

[devop]

precision is what I concerned more about,
can I say there is no precision difference between these two software ,but between the module we can get?

 

[redswat]

hspice is a popular and accurate tool,
if simulate a large netlist,i use starsim

 

[renwl]

yes,it's right.
I use virtuso to layout the design. Is there any another analog layout tool?

 

[wjlzhx]

I use both of them
but in most time i use spectre
because it is easy to use

 

[pit1000]

I think it is necessary to pay attention on post-layout simulation. If you use AssuraRCX with netlist for spectre to work more pleasantly, than with netlist for spice. As a rule, two programs from one vendor are friends more strongly, than two - from different.

spectre

 

[hackjiang]

I think HSPICE is better.

Spectre GUI is more friendly , but hspice is better for designer to let you know what parameter is to do. Laker is good layout tool for SOC.
