SystemC-AMS:sca_linear_solver error in modeling of PLL

[Shashank]

Hello all,

I am trying to model a simple PLL in SystemC as well as SystemC-AMS.

Currently i am working on Charge Pump part of it. But i am seeing an error during execution. I am able to make all the files. But when executing the .exe file, the error of sca_linear_solver is seen. 

Have seen posts in this forum on similiar errors. But those were involving inductors etc. which needed to have initial conditions mentioned i suppose. I have tried the initial conditions in my components like off_state in sca_eln::sca_tdf_rswitch or the frequency of the DC source. Attached is the snapshot of the error and source codes.

Please help to rectify the error.

Thanks,
Shashank

Hello,

 

Please replace all the caps defined as for example C1 = new sca_eln::sca_c("C1",1.0); with C1 = new sca_eln::sca_c("C1",1.0, sca_util::SCA_UNDEFINED); and then try again

There are two current sources in series (I1 and I2 via M1 and M2) - this is not possible due potentially they can define different currents.
