I want to know how to write hspice code to get voltage gain(vout/vin) and phase versus frequency in op-amp. could you give some simple example??
Behavioral modelling is an extension to original Berkley SPICE and unfortunately handled different by SPICE variants. The hspice behavioral sources syntax is described briefly in the Simulation and Analysis user guide.

Hi, I want to extract the S-parameters of a mixer using hspiceRF. I considered using the HBLIN command (haramonic balance method for S-parameter extractions). According to the hspice user guide RF Analysis 2010, I have defined a Port element with the HBLIN portion of it which is as below: p2 IFout 0 port=1 HBLIN=(1,1) (...)
Just run your MC analysis; after its completion the simulation log output will tell you where you can find the results. This depends on your hspice set-up.
hi, guys: how can i simulate ibis in hspice, i have got an ibis file of analog switch, and how can i connect the ibis file to my "trace" model? .......................... | ********************************************************************* | Model SWITCH1 | *******************************************************************

See this hspice? user guide: RF Analysis manual, chap. 7 .
how can i model power supply noise in hspice? thanks
The hspice? user guide: Simulation and Analysis (B-2008.09) on pp. 237-239 shows several examples of behavioral (E-element with a SIN source) and Verilog-A examples. It could be as simple as Eosc n+ n- VOL='SIN(1+cos(freq/T))' ... but I'm not sure if it works with changing frequencies. Just try it!
Hi all, I want to setup + or - n*sigma only in monte carlo hspice. Can anybody help me how to do setup? Thanks,

Hi everybody! I am learning to use Synopsys hspice. I would like to do a transient analysis on a circuit including the parasitic data contained in a .spef file. I have read on the user guide about the possibility of invoking the post-layout back-annotation with the options BA_FILE, BA_TERMINAL, etc. In the guide there are (...)
One way to do this is using the .ALTER command to run a simulation for each V you want (see the hspice user guide: ). The results will be extracted to a file and you can take the slope with a spreadsheet software or by making a script in perl, python, ....
Hi Everyone, I try to run an example from hspice@RF user guide. It is example 2, Power Amplifier. .options POST accurate .param f0=950e6 PI=3.1415926 Ld=2e-9 Rload=5 Vin=3.0 .param Lin=0.1n Vdd=2 Cd='1.0/(4*PI*PI*f0*f0*Ld)' M1 drain gt 0 0 CMOSN L=0.35u W=50u AS=100p AD=100p +PS=104u PD=104u M=80 Ls in gt Lin $ gate tuning Ld (...)
HI, guys, Do you know about how to perfom a monte-carlo analysis on a comparator's offset by hspice? I want to get a picture like the one below, it is got from P.E.allen's book. Thank you for any comment.
Hi~~~ is anybody know how to see current phase in hspice i only find .print vp(node) , it can only see the voltage phase thanks a lot !

you can google hspice manual

you can download some of that from edaboard eldo, spectre and hspice pspice is mainly for accurate analog simulation, they are simulators. eldo and hspice can integrated into cadence analog environment-artist. On pc platform, we mainly use hspice and pspice. Design flow: basic concepts, basic books, then practical books and (...)
