GTS Transceiver Simulation Model Encrypted file - unable to decrypt with Cadence Xcelium

​Hi everyone,

I am working on integrating the generated simulation models of the Agilex-5 GTS PMA/FEC Direct PHY IP with our main IP. I have encountered an issue where an encrypted file within the models cannot be decrypted by the Cadence Xcelium Simulator.

The file is located at:
<ip>/n_channel_superset_2100/sim/intelfpga/intel_src_flow_ctrl.sv

I have tested this with Cadence Xcelium versions 19.x, 20.x, and 22.x, but the decryption error persists across all versions. We are currently using Quartus Pro Edition 2026.1.0 with an evaluation license.

Could you please provide guidance on how to resolve this decryption issue?

Thanks,
Arun
