Powered by our custom RouteIQ Engine, integrated with the Hungarian Algorithm, the system delivers a structured multistage work flow encompassing signal planning, layer optimization, and tester channel mapping enabling intelligent, highly efficient ATE PCB routing.

The conventional development cycle of Automated Test Equipment (ATE) interface PCBs is highly dependent on manual processes, particularly during the critical stages of signal layer planning and tester channel assignment.

• Time-consuming & error-prone

• Complex constraint management

• Poor optimization

• Reduced efficiency

• Lack of automation

Modern EDA tools simplify schematic and layout design but still lack automation for signal layer planning and tester channel assignment both essential pre-routing steps in ATE interface board development. This work introduces a smart automation framework that performs these tasks with minimal user input while complying with constraints such as anti-pad spacing, routing boundaries, and signal-integrity requirements. The underlying algorithm operates in a structured, constraint-aware manner, systematically planning DUT signal escapes and assigning tester channels to achieve optimal trace utilization and minimal layer count.
