Anyone tried to run simulation on PC and SPARC? I tried and find that the results are different for switching capacitor circuit. Anyone has same experience?apdjeppra apdjeppra apdjeppra apdjeppra Thanks |

| 1 | fujun2013 | I have simulated in PC before, and find the result not so good... I think SPARC has more accurate result |

| 2 | bubulu | I think main reason lies in bad mathematical models. Please check used models. | 2008/8/28 06:06 |
| 3 | knoxville | I am using BSIM3.3 Model. I think the models are OK since I get same result for some other circuit in AC and transient analysis. But, for switching capacitor circuit, I get different results. | 2008/8/28 06:06 |
| 4 | ct731 | please check your option seting and transient step and transient periors! |

| 5 | hualeyan | Both files are the same, model, simulation card, circuit netlist. Everything is the same, in the same directory | 2008/8/28 06:06 |

| 8 | knoxville | Today, i even found that the results on P4 and Athlon are different! Both simulations are on Win 2K and model, netlist, simulation card are the same. I use HSPICE because of its proved accuracy and good convergence. In fact, I tried HSIM before, it is several times faster than HSPICE, but for some circuit like switching capacitor circuit, the results are obviously wrong. |

| 9 | z315 | Avanti local agent provide different prices in PC and UNIX version. PC version's list price is about US$8000 and UNIX is double of PC's. And the sales tell me that some limit in PC's version. BTW, u may upload the lib and encrypted hspice in the forum to let others help u to test the case. Maybe the problem is only in ur enviroment. |
