The board decides what the firmware can do

The hardware a product is built on sets the ceiling on everything above it. A power rail that sags under load, an I/O interface that cannot meet timing, a sensor path with more noise than signal — none of those are firmware problems, but they all arrive disguised as firmware problems.

CircuitForge covers electronic architecture and the design work that follows from it: schematic capture and PCB design, or review of a design somebody else has produced before it goes to fabrication. Power, analog and digital I/O, sensor interfaces, and communications are the recurring territory — the parts of a board where a small mistake is expensive to find later.

FPGA and CPLD work sits here too. VHDL logic design, SoC integration on parts carrying a processor and fabric on the same die, and the interface between what the fabric does and what the software expects — which is where a surprising share of system-level bugs actually live, because it is the one boundary neither the hardware side nor the software side fully owns.

Then there is the bench work: finding out why a board does not behave the way its schematic says it should, with an oscilloscope, a logic analyzer, and a hypothesis. Design review before fabrication is cheaper than debug after it, which is why CircuitForge is often engaged for a review pass alone.

Because the same firm writes the firmware, an electronics problem can be attacked from both sides — instrument the software to provoke the condition, then measure it on the bench. That loop is slow when it crosses a vendor boundary and fast when it does not.
