Check the exact restriction
The maintained manual documents variable-step support for PHASE analysis with BDF integration. LOSSLESS transmission lines block this mode; an untyped T element defaults to LOSSLESS.
Choose a valid run
- Read the diagnostic's list of blocking lines and check the model assigned to each.
- Use a validated fixed-step setup for LOSSLESS lines.
- Use LCLADDER only when its finite LC-ladder approximation is physically appropriate. Do not change the model merely to silence the restriction.
- Repeat the calculation with a smaller nominal step when validating edges or amplitudes; accepted settings alone do not establish convergence.
