  • Re: VerilogA compiler
     Thank you for your help. It works with me now, but the question is can I use ddt and ddx to model the differential equation? I'm asking this question because ddt gave me unexpected result, I use it to test when the curve reached the stable point (becames fixed to a certain value for the rest of the simulation) so I expected the ddt to ...

  • Re: VerilogA compiler
     Thank you for your reply Actually I ran the following and I'm still have the error of "Error found by spectre during AHDL read-in.     ERROR (VACOMP-1554): "/home/thesis/Chua3/CalculateTheWeightR12/veriloga/veriloga.va", near line 25: Encountered an attempt to access a quantity that depends on a time ...

  • Re: VerilogA compiler
     Thank you so much for your help, I'm going to try this model and see. I have one more question please, when I execute the "ddt" operator inside if statenment it gives an error , I need the derivative to be zero as a condition to implement some code, any idea ?  Thank you again,

  • VerilogA compiler
     Dear all, I'm using VerilogA model in my design in Cadence, I have some variables in the model that should be changed with time, actually I have two questions: 1- Is there a way to display the value of those variables during the analog simulation? I was looking for VerilogA compiler to test my code first but I didn't find, can ...

  • Re: simple RC circuit
    Thank you so much Marc for your help and support, I'm going to check the "rforce" parameter and do the simulation again. Best regards, Sali

  • Re: simple RC circuit
     Dear all, I tried another example but this time with a DC source it didn't work properly until I changed the options under the transient analysis tab. The circuit and netlist is attached below. Thank you in advance,   The netlist: // Generated for: spectre // Generated on: Apr  1 14:27:58 2014 // Design library name: ...

     Dear all, I have another result when I modified the options under the transient analysis tab, but I need more explination to why the results are different now, please check the file. This is the netlist file // Generated for: spectre // Generated on: Apr  1 14:36:52 2014 // Design library name: Chua3 // Design cell name: rc // ...

  • Re: simple RC circuit
     Thanks KarthikJaiho , actually I'm still looking for the reason for this result, I was working in a large circuit that gives me a result different than the manual one, at the end I tested this simple circuit and I found this error which I didn't expect. Thank you again for your help.
