Enterprise PCB TCO: Comparing CAD and AI-Assisted Workflows

An enterprise PCB comparison should evaluate complete workflows. Cadence Allegro and Siemens Xpedition provide native design environments; adding Quilter automation does not automatically remove the need for those tools. Compare the existing CAD workflow with CAD plus automation, including all work required to reach the same release criteria.

Collect evidence before comparing totals

• Obtain quotes for the required CAD configuration, maintenance, support and deployment.
• Measure preparation, placement, routing, review and release effort on representative boards.
• Include training, library work, integration, security review and administration.
• Record prototype and rework expenditure within a consistent project boundary.

Use actual contract terms instead of public entry prices for a different product tier. Quilter's pricing page describes project-based pricing linked to pins to route. Request pricing for the actual board and deployment; do not assume a generic annual automation subscription.

An inline worksheet for a fair comparison

Create one column for the current workflow and one for the proposed workflow. Add rows for retained CAD costs, incremental project fees, active labor, integration, training and included build costs. Separate one-time adoption expenses from recurring costs, and specify the period being compared.

Workflow cost = software and service fees + active labor + adoption costs + included build and rework costs.

Incremental net benefit = baseline cost − proposed workflow cost.

Hypothetical example

Suppose a program uses 1,000 active hours at a loaded rate of $120/hour: $120,000 of labor. An alternative scenario of 800 hours represents $96,000, or $24,000 of released capacity. If incremental automation and adoption costs total $15,000, the modeled net benefit is $9,000. CAD costs that are unchanged remain in both totals and cancel in the difference.

These are illustrative assumptions, not vendor quotes or measured Quilter performance. If the pilot does not achieve the assumed hours, change the model. Capacity has operational value, but it reduces cash spending only when expenditure actually falls.

Keep schedule value out of the direct-cost subtotal

Do not subtract speculative launch revenue from a tool invoice or count saved labor twice. Model a delivery-date scenario separately: identify the critical path, establish whether layout changes it, and state the assumptions connecting earlier delivery to business value. Use low, central and high cases rather than one guaranteed revenue number.

Make the buying decision reviewable

Retain quotes, input revisions, effort logs and acceptance reports. Run a representative pilot before committing to a rollout. A transparent model can show where automation helps, where specialist review remains necessary and which assumptions most affect the decision. The worksheet above can be recreated directly in a spreadsheet; no separate calculator download is required.
