PADS I/O Designer is for designers implementing complex field-programmable gate arrays (FPGAs) on PCBs. Is said to decrease design cycle time. Reportedly cuts high-end FPGA time-to-market, improves systems performance up to 50%, and reduces PCB layer counts.

Enables concurrent FPGA and PCB design. Defines FPGA-PCB interface with a variety of correct by construction, drag and drop PCB signal to FPGA pin assignment methods. Synchronizes the interface across the FPGA and PCB flows through Automatic DxDesigner and schematic generation, and automatic generation and maintenance of required FPGA vendor, HDL and synthesis constraint files.

Options include PADS layout physical design importing for FPGA vendor rules-driven pin swaps, and optimizing multiple FPGA interfaces simultaneously within a single PADS layout physical design.
