HSPICE (from Avant!) offers a more robust, commercial version of SPICE. No free copies here. If interested, contact Avant! This popular version of SPICE, available from Orcad (now Cadence) runs under the PC and Macintosh platforms. An evaluation version, which can handle small circuits with up to 10 transistors, is freely available. Hspice Free Download For Windows. The software is included in Education Tools. This PC software works fine with 32-bit versions of Windows XP/Vista/7/8/10. The actual developer of the free software is Cadence Design Systems, Inc. Design and simulate analog and digital circuits.

- Download the book’s available HSPICE simulation examples in HSPICE_CMOSedu.zip.
- To ensure that HSPICE generates a data file for Avanwaves or Cscope add “.option post” to a netlist
- HSPICE netlists end in an “sp” (e.g. mynetlist.sp)
- HSPICE uses Level=49 for BSIM3 and Level=54 for BSIM4
- Syntax for a switch in HSPICE is:
![Hspice Hspice](https://webforpc.com/wp-content/uploads/2015/09/Windows-8-Free-Download.png)
GS1 n1 n2 VCR PWL(1) CLOCK,0 0.499,1m 0.501,10G
For example, if the voltage difference between nodes CLOCK and ground (0) transitions through 0.5V the switch, connected between nodes n1 and n2, will go from a short (1 milliohm) to an open (10 Gigaohms). https://downyload508.weebly.com/hopmon.html.
The Electric VLSI Design Information
- Below shows how Electric is setup where the Run Program path is (for example): C:synopsysHspice_A-2008.03-SP1BINhspice.exe
- Note that while the Run Program field is not case sensitive the “with args:” field is case sensitive (so use the uppercase names as seen)
- Also note the difference between the “with args:” field seen below and what is used with LTspice
- Electric outputs netlists with a *.spi extension.
- If you get an Exception Caught! when Electric loads simulation data it likely means that you have run out of memory. See number 15 here for how to increase the memory allocated to the JVM
Running HSIM from the command window (Start -> Run -> then type Cmd) in Windows
Free Windows 8 For Students
- Ensure the HSPICE model levels are used as indicated above (e.g., BSIM3 is Level=49 instead of Level=8)
- Use exact same netlist as used with HSPICE simulations except replace .options post with .print v(*) Level=1
- .print v(*) Level=1 saves node voltages from the main, or top level, cell. Level=2 stores node voltages from both the top level cell and the cells directly instanced in the top level cell (Level=3 stores the top three levels of hierarchy, ect.)
- HSIM can be run from the command prompt as seen below
- The errors can be viewed using a text editor in hsim.log
- The simulation output, hsim.fsdb, can be viewed using CosmosScope
- See the HSIM manual covering invoking HSIM for additional options
- If you get an Exception Caught! when Electric loads simulation data it likely means that you have run out of memory. See number 15 here for how to increase the memory allocated to the JVM
