Hello MohMor,
Sorry I did not see the last error: Error detected by hpeesofsim during TRAN analysis `Tran1'
I haven't seen this error before but I have found this solution in another forum:
"Sometimes, when ADS is performing an instantaneous simulation, the simulator will report an error, this situation usually means that during the simulation process of one or more nodes in the circuit structure, the frequency of signal changes exceeds the minimum time set by the simulator.
Solution: You can try reduce the emulator step."
If this does not work I recommend that you post your question in the Keysight Advanced Design System Forums.
