Choose the extraction goal and required electrical setup

Choose the quantity before changing Mode

The extraction goal selects a formulation and the electrical setup shown by Basic. It does not convert geometry, material assumptions, a circuit network, conductor names or a frequency sweep into another physical problem. Start from the complete matching example and preserve the correct fabrication process.

These checks use a frozen Windows Studio/Core 8.0.2 candidate. The download is a complete synthetic MQS network with inline geometry and two ordinary P1/P2 labels. Its deliberate mode-only variants demonstrate setup requirements; they are not accepted complete models for the other formulations.

Save intended source changes and inspect current diagnostics before a calculation. Basic file/setup status and a successful Save do not establish physical validity. The capacitance numerical reference remains withheld while KB-EQS-001 is open.

Match the goal to its required model

Use the Basic selector and inspect the resulting source

1. Open the complete saved IXI and choose Basic > Extraction goal. Select the goal matching the requested physical quantity.
2. Inspect Raw IXI. In the checked teaching model each selection changed only Mode; the geometry, P1/P2 labels, process and netlist references remained unchanged. Save a separate diagnostic copy if exploring another choice.
3. Choose Electrical setup and read the current visible mode panel. Review inputs, geometry labels, netlist or response block and frequency settings appropriate to that choice before requesting a solve.
4. If an existing Mode should be removed, inspect and edit it in Raw IXI. Selecting Choose later on the existing MQS model leaves its source unchanged, returns the selector to MQS and displays Clear the extraction mode in Raw IXI. Choose later is a deferred choice when creating a draft, not a clear command for an existing project.

Keep an MQS network separate from field-only inspection

For mapped inductance/resistance, inspect the extraction circuit and its port-to-layout/inline topology. The complete teaching model uses strip.cir and matched P1/P2 declarations. Its baseline, recovered and separately reopened native runs all report 3.89648 pH against the 3.9 pH fixed design; that is a bounded comparison, not convergence or process calibration.

Run without a netlist for current/field inspection changes NoNetlist in the source. The actual warning says these runs do not produce mapped inductance or resistance results. Basic can report Complete for that deliberate policy; it does not mean a circuit network was extracted.

The checked control was enabled only as an unsaved setup edit. Normal Undo restored the exact original MQS network source before saving a separate recovery and solving it. No field-only solve is claimed by this workflow.

For EQS, supply conductor declarations

EQS uses the conductor labels rather than the MQS circuit mapping. The maintained parallel-plate example has C1 M0 and C2 M1 labels in inline IXI geometry. Review the actual layer, position, connectivity and dielectric model in that complete example.

Changing only the teaching strip’s Mode to EQS leaves P1/P2 untouched. The current panel finds no capacitance-conductor labels and reports Incomplete. This is the intended diagnostic comparison; it was not solved and no capacitance value is presented.

In this inline-only comparison, the panel’s Layout import row says Not selected/Unresolved. It describes the absent external import. Inspect Raw IXI and Basic > Input files for inline geometry rather than adding an unnecessary GDS file to silence that line. The conductor requirement still needs its own correction.

Follow the parallel-plate guide for its complete setup and retained limitations. KB-EQS-001 keeps its numerical reference withheld pending output review.

For S-parameters, define a response and its ports

EMQS and FULL use the frequency-domain response setup. Inspect $SPARAM, the frequency range, number of steps, linear/decade sweep mode, reference impedance and at least one named port. Components and less common settings remain available in Advanced setup.

The mode-only teaching copies have no $SPARAM block, so both panels report Incomplete. The FULL panel retains its explicit full-wave explanation; the EMQS panel explains the quasistatic formulation. Neither was solved here.

Add minimum $SPARAM setup is offered when the record is absent. That action was not requested in this check, and a minimum record would still need the intended named physical ports and frequency configuration. Use the complete S-parameter examples and linked frequency/output guidance for that work.

Treat Z0 Complete as a count check

Z0 combines inductive and capacitive solutions. Its guidance says only the first two impedance ports read are used, recommends outer-edge terminals, and leaves their placement, polarity, connectivity and order for inspection in the model.

The unchanged teaching geometry has two ordinary combined labels, P1 and P2. Basic detects both and reports Complete. It also says the geometry and polarity must be verified. That status is not a characteristic-impedance result or evidence that this MQS example has become a valid Z0 model.

Review the appropriate complete impedance example, its process/geometry and port order before solving. This workflow captured the actual detection/guidance only and did not run a Z0 calculation.

Recover the intended model before running

1. Return the teaching selector to Inductance and resistance. If the field-only checkbox was changed, Undo that edit and inspect Raw IXI so NoNetlist no longer overrides the intended network setup.
2. Save the restored source as a separate IXI beside the same process.ldf and strip.cir. Review inputs, electrical setup and current diagnostics; preserve the original source and deliberate diagnostic copies.
3. Run the restored MQS network and inspect its current result. The recorded recovery matches the baseline parsed L1 value exactly. A separate normal Studio process explicitly reopens and reruns the saved recovery with the same value.
4. For a different intended calculation, use its complete model and applicable reference instead of treating a changed Mode, a count badge or an old result as success.

Use the complete diagnostic example from an agent

The three downloadable plain-text inputs are the same complete MQS baseline used by the native checks. An agent can inspect Mode, geometry/label records and file relationships directly. Deliberately changed-mode copies belong in a new writable directory and must remain labelled as incomplete diagnostic models until their physical declarations are supplied and verified.

Preserve the saved source, complete dependencies, intended quantity/units and actual runtime with every result. The native workflow supplies control/source and MQS recovery evidence; it does not qualify a new CLI command, another formulation or an automatic model converter.

Check the result

The selected formulation agrees with the requested quantity and the actual electrical declarations. Read the current visible panel and source; supply missing conductor/response information and independently inspect physical port properties. A saved mode, Basic Complete or successful file check alone does not establish a valid numerical result.

If the problem remains

Return to the complete example for the intended calculation, inspect the first current diagnostic and compare its physical declarations with the source. Restore the original model or correct a separate copy deliberately. Keep the EQS output hold and all numerical/release limits visible.
