Annotated .xdc, .sdc, .lpf, and .cst templates for every interface — with the theory, formulas, and toolchain guidance engineers actually need.
Paste datasheet values — tCO, tSU, tH — and get the exact set_input_delay / set_output_delay lines. Shows setup and hold slack with a visual timeline. No guessing what the formula is.
Open CalculatorPaste your Verilog or VHDL top-level module. The AI reads every port, identifies clocks and interfaces, maps pins to your board, and writes the complete constraint file in seconds.
