电路在附件里面。下面是问题的描述。大侠出手!
Circuit:
A pulse goes through an RC filter and drives an inverter that is formed by a resistor and a NPN transistor.
Symptom:
1. Simulation runs successfully. Everything is saved, then Altium closed. Re-open Altium and try to run simulation again. Errors pop up.

2. Double click C1, select Simulation under models, then click edit. Checking the tabs, do nothing and close. Run MultiSim again. The first two errors above will be gone.

3. Do the same for BJT Q1, voltage sources V1 and V2. Do nothing except looking at the Sim Model window. Run MultiSim and everything is OKAY. No more errors.
4. Save everything and close Altium. Open Altium, try to run MultiSim, all the errors will pop up again.
5. Please note, in Altium Winter 09, the above errors do not exist. |
