Automated design quality scoring, auto-generated documentation, structural fault coverage analysis, and intelligent test point placement — before layout begins. Tomachie offers something for all product team members, from design engineering teams to test engineer. The design improves and Tomachie delivers deterministic fault coverage analysis across every major test and inspection method.

MOUNTAIN VIEW, Calif., April 27, 2026 /PRNewswire-PRWeb/ -- Tomachie announced its AI-Assisted PCB schematic design analysis platform, enabling engineering teams to evaluate and improve schematic quality before layout begins. Schematic errors caught after layout — or in production — cost 10 to 100 times more to fix than those caught during schematic capture. Supporting Altium, KiCad, and other schematic tools, Tomachie accepts privately encrypted design uploads for automated assessment of electrical intent and downstream readiness.

Schematic Design Quality

Tomachie handles any design complexity — flat, hierarchical, multi-sheet, harness-based, and bussed architectures — establishing a measurable quality baseline that reduces downstream friction across the product lifecycle. Library quality checks grade model correctness and verify IPC land pattern compliance. By enforcing schematic correctness without restricting architectural choices, Tomachie reduces repeat review cycles and minimizes interpretation errors during alternate part swaps, test generation, and production handoffs.

Electrical and Interface Verification

The platform performs over 400 automated design checks spanning low-speed serial interface (LSSI) verification — I²C pull-up validation, JTAG TAP selection, EMC shield-to-logic GND handling, SPI controller/target configuration, termination errors on clock lines, and output-enables tied directly to power/GND planes. High-speed serial interface (HSSI) nets are identified, avoided during intelligent test point insertion, and collated for engineering team documentation.

Automated Documentation Generation

Tomachie auto-generates document editor-ready tables of connector pinouts, power distribution summaries, I²C address maps, JTAG chain documentation, SPI controller/target tables, HSSI interface tables, and designer-annotated net documentation — reducing manual effort and improving communication with production, test, and non-technical stakeholders.

Structural Fault Coverage Analysis

Tomachie provides deterministic visibility into structural fault coverage across all major test methods — predicting solder fault coverage for manual inspection, AOI, and AXI; generating shorts and opens analysis using boundary scan (IEEE 1149.1, 1149.6, 1149.10) with and without loopback; and determining electrical fault coverage for flying probe, in-circuit, and Intellitech JAF® ATE using bed-of-nails or connector access.

Intelligent Test Point Insertion

A key differentiator is Tomachie's intelligent test point insertion engine. Based on user-defined policies and existing boundary scan access, it automatically identifies fault coverage gaps and inserts the required test points — giving layout teams precise guidance for area planning before the first component is placed. Policies support all-nets coverage, power rails only, and exclusions for HSSI and DDR memory. When not using a test-point-per-net strategy, the platform inserts test points where they deliver the most value.

Who Benefits

Design engineers catch substantive errors before they propagate. Engineering managers achieve consistent quality across in-house and contract designers. Production and test teams benefit from designs optimized for consistency, with functional testing focused on defects structural test cannot cover — all without anyone appearing pedantic about schematic correctness.

"Some may say 'experienced engineers don't make these mistakes.' In every design we've analyzed, we've found substantive issues — shell grounding errors, JTAG select problems, missing I²C pull-ups, passive values in comments, hidden NC pins, missing GND pins, non-compliant footprints – using imperial notation but metric dimensions. The tool doesn't replace experience; it catches what experience alone misses under schedule pressure and other factors."
