BER and EVM calculation

Hi,

I hope you are doing well.

I have designed and simulated a PA system in Cadence using high-level blocks, which include both ideal components and some defined with Verilog-A. My goal is to calculate the Bit Error Rate (BER) and Error Vector Magnitude (EVM) in the system. I am using an LTE source from RFLib, and everything functions correctly in the transient simulation.

To calculate these parameters, I intended to use envelope simulation. However, when I attempt to run the envelope simulation, I encounter convergence errors, which prevent it from working as expected.

Given this issue, I believe I need to work with transient data instead. Could you please advise on how to approach this in Cadence without exporting the data to MATLAB?

Thank you for your assistance.

The wireless probe is only intended to use with wireless analysis (i.e. an envlp analysis).

Perhaps you should contact customer support so that we can help you resolve the convergence issue? Transient will be much less efficient because of the need to simulate every cycle.
