a random pulse generator in HSPICE

you can use stimuli also, refer to "hspice? user guide: Simulation and Analysis" document

Gain, Phase versus frequency analysis

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??

convert pspice model to hspice model

Hello! Could you help me convert the following pspice code to hspice code especially the 'Bxx' dependent sources. .subckt MODEL 2 1 Bset 1 10 v={v(31)*12} Rint 10 11 0.1 Vsen 2 11 DC 0 Cf 0 20 1e-6 Rf 20 21 1e6 Bf 21 0 v={i(Vsen)/1} Cchrg 0 30 {3600*1} IC=1 Blost 30 31 v=v(20) Bvsen 31 0 i={i(Vsen)} .ends Thanks in

Using "HBLIN" command in HSPICERF

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) (...)

Monte Carlo Analysis

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.

simulate series switch of ibis in hspice

Hi, In order to simulate your IBIS file in hspice, then you need to create a hspice deck. The syntax of which is specified in the hspice user guide. Alternately you can even simulate it in cadence using the ibis2spice utility and simulating it in spectre. Or else you can even convert the IBIS model to spice (...)

power supply noise modelling

how can i model power supply noise in hspice? thanks

how can I implement such a model in cadence virtuoso?

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!

How to setup + or - n*sigma in monte carlo hspice

I want to setup + or - n*sigma only in monte carlo hspice. See e.g. hspice? user guide: Simulation and Analysis B-2008.09 , p. 318 . If you just want MC runs for e.g. -3σ and +3σ, you could use (for a transient analysis): .tran 10p 1n sweep sigma -3 3 6 .tran 10p 1n sweep monte=100

Hspice back-annotation

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 (...)

Hspice - to find slope

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, ....
