Thread: The D/A simulaton of Hspice

Does anyone know how to use vector in the Hspcie , runthe D/A simulation , And anyhave sin code for D/A simulation using Hspice , Thanks

The easiest way to generate the code for your D/A simulation is to build an ideal ADC with a sinewave input source. Then use its output to drive your DAC. HSPICE should have macro model capability to handle this.

I design D/A

simulation ramp for INLD/DNL --> use PULSE ..

sim sine wave for SNR --> use table code

but I think use behavior A/D is better .. but how modeling behavior A/D ?
when I design flash A/D .. I use hspice and make a behavior D/A model .. I find I can not use "if else .. for decode circuit ..."

finally I use verilog and synthesis a real decode , and convert to spice
for behavior D/A model ...

if hspice support some behavior language (if else .. when .. for next ..)
I can make model easy ..

Excuse me , Do the HSpice has easy method to do bevior A/D for real D/A , Do yo have any example ?/ Thanks

I use VCVS make a idea comparator ..
but hspice no ideal "switch " , you need a behavior switch ..

detail please see hspice manual ..
