    Encounter RTL Compiler

    I am using Encounter RTL Compiler Version 10.1. I am getting the following warning message as a result of using the command (report ple). This warning message is about the tool dropping certain metal levels and it looks like the following: ** = 'M1' is dropped because its Resistance/Length...

    MATLAB-HSPICE interface

    Hello all, Is it possible to prepare a perl file, run it to run simulations in HSPICE and read the output back into MATLAB and use the data to continue to do simulations without going through each step manually? Thanks!

    Read inverter Capacitance/32nm BSIM4 MOSFET model in HSPICE

    Thank you... I have another question about HSPICE. Is it possible to print the parasitic capacitances such as the gate to drain capacitance, drain to bulk capacitance etc. Surely, SPICE takes these into account and calculates each of these at the background, but is it possible to print the...

    Read inverter Capacitance/32nm BSIM4 MOSFET model in HSPICE

    Hi, I'm using the 32nm BSIM4 silicon MOSFET model to make an inverter in this technology. I'm trying to read the input capacitance of this inverter, but if I run a transient analysis and print the capacitance at the input node of the inverter using cap(input node), the values that I get are...

    Determining parameters from BSIM model

    Hello, I'm using HSPICE and BSIM4 MOSFET models to simulate an nmos. If I want to find the gate capacitance of an nmos when it is ON, would it be enough just to read the capacitance at the gate node of this device when Vgs and Vds are set at Vdd? Thanks

    suggestion needed for BSIM4 in hspice

    I mistakenly changed the handle twice, you're right. I corrected it and ran the whole thing again and the simulation aborts with an error, so I guess it is using the model file. Level 54 corresponds to BSIM4 model, so the results that I get should be what I'm really looking for. Thanks.

    suggestion needed for BSIM4 in hspice

    Thank you very much. I changed the line and replaced nmos with nmos4 both in the PTM file and in the instantiation in my netlist file and the simulation results are the same as the ones that I got when I was using nmos instead. So, I'm not really using the BSIM4 library. I will be looking into...

    suggestion needed for BSIM4 in hspice

    Thank you Keith, this has been very helpful. I was able to run the simulation for a simple netlist at the moment. I'm writing now to clarify all the questions that I have in my mind. Apparently, I was confused about where to find the library files. It seems that the parameters in the .pm files...

    suggestion needed for BSIM4 in hspice

    Hello, Keith. Thank you for such a quick response. I have downloaded the source code at **broken link removed** for BSIM4.6.4. This is a C code. I am going to use the model cards from PTM at http://ptm.asu.edu/ for different technologies. I was expecting to find a .lib file written in SPICE...

    suggestion needed for BSIM4 in hspice

    Hello, I'm new to using BSIM. I just downloaded the source code for BSIM4 and I have no idea how to run this code and use HSPICE to get results. Could you please point me in the right direction? Is there a readme file that explains the set up? Thanks.
