Simulation does not start
- Run ERC and resolve missing ground, open pins, and invalid component values.
- Confirm the selected analysis has the required source and time or frequency settings.
- For convergence failures, use the solver guidance instead of repeatedly increasing tolerances.
Scope is empty or stale
- Select the Scope view for the analysis you just ran. Bias Point results use a table instead of waveform traces.
- If a view shows No run, run the associated analysis and wait for Simulation complete.
- Open Signals and add a signal after a graphical analysis completes. If the picker says No signals are available in this category., run the corresponding analysis first.
- If the status says Stale or Simulation complete, stale, run the analysis again after your edits. A view keeps its old data until its associated analysis runs again.
A model does not import or simulate
Review the terminal mapping, parameters, and reported import error. OhmSpice accepts textual SPICE models, not encrypted, executable, or externally dependent files. A successful compatibility check does not prove model accuracy.
Python trust, errors, or cancellation
- An imported, shared, or changed script requires Trust and run after you review its source. Opening or viewing a project does not run Python.
- If Script status shows Error, expand the Console and read the traceback and marked line. Correct the source, choose Save, and run it again.
- If the Console offers Reset Python runtime, choose it and then select Run. This restarts Python.
- Select Cancel to stop a running script or sweep. The status becomes Cancelled; run it again for a complete result.
- Each analysis has a 15-second default timeout. Shorten the run or pass a larger
timeout=value when the work is expected to take longer.
Simulation or storage is unavailable
- If the Console says Simulation error or Simulation engine stopped, expand Console and select Run again. If the same error repeats, include the Console output in a bug report.
- If saving reports Browser storage is full, free browser storage and try again. If OhmSpice storage is locked by another open tab, close the other OhmSpice tabs and reload.
- If an editor panel says it is unavailable, choose Retry. If the problem continues, choose Reset to reset that view.
- If a project problem offers Export recovery copy, save that copy before reloading. A project load dialog may also offer Save original file.
Verification or recovery link fails
- On an email link, confirm that you opened it intentionally, then choose Continue. The link is used only after you continue.
- If the app shows Link could not be verified, Account setup link expired, or Recovery link expired, choose Back to sign in and request the latest link.
- For password recovery, choose Forgot password?, enter your email, and select Send reset link. On Check your email, use Resend if needed, then open the newest message.
- For an unconfirmed account, return to Sign in and enter the same email and password to send a new verification link. Cloud saving and sharing remain disabled until verification.
Manufacturer Parts are unavailable
- Manufacturer catalog search requires a signed-in, verified account. Choose Sign in when prompted.
- If the catalog shows No matching Parts, broaden Search Manufacturer Parts or switch Browse by between Categories and Manufacturers. Use Open full search for a broader list.
- If a model cannot be delivered, select Open manufacturer model page, download the unchanged model file, and return to select Choose downloaded file or I already have the file.
- If the catalog shows Catalog unavailable, choose Retry. The vendor import flow remains available when you have a compatible textual model file.
What a bug report includes
Open the Help ribbon and choose Report bug. Description and category are optional. Automatic diagnostics contain app and error details, not project bodies, netlists, scripts, simulation vectors, typed form content, clipboard content, credentials, or tokens. Include the current circuit and Add screenshot… are optional attachments. Review them before sending and use Remove screenshot when you change your mind.
If the in-app report cannot be sent, email [email protected].
Cloud actions are unavailable
Cloud save, My Library, Manufacturer Parts, feedback, and private sharing require a verified account. Retry after confirming sign-in and email verification. Local drafts remain on the device when signed out.
A private link does not open
Sign in with the account that the sender invited. Ask the sender to confirm your email address and resend access if needed.
