• Verified that all four driver channels already exist in the project: U1, U2, U3, and U4, with the expected support parts for each channel.
• Confirmed the PCB placement pattern for the power devices: U1, U2, U3, and U4 are all placed with the same 270 deg orientation.
• Retrieved the actual schematic net mapping for the channel interfaces so the intended module terminals can be tied to the existing project nets correctly.
• Ran layout validation checks and confirmed the board is not currently clean: airwire review reports 77 errors, and overlapping-copper review reports 244 errors.

• ✅ Confirmed U1 remains unchanged so far
• ❌ Could not perform the required U1-to-module conversion and instantiate new reusable copies because there is no available tool in this environment to create PCB modules or duplicate/freeze a routed PCB channel as a reusable layout block
• ❌ Could not make all channels pass DRC/airwire, because the current validation issues are tied to PCB geometry/routing objects and this environment does not provide direct PCB trace/copper editing to resolve them

“A module is a block containing a complete design section, including parts, traces, vias, etc. These blocks can then be placed into existing projects to reuse previous designs with minimal effort.
This idea of PCB layout reuse is a great way to help designers build things faster. If you wanted, you could go back into your library of PCB projects, mix and match the modules you need in a new project, and arrange it all in a new PCB.”
