FMCW chirp sequencer
Maturity simulatedTargets FPGA + ASICDifficulty MediumPriority 1
Digital ramp generator that programs a fractional-N synthesizer through chirp profiles (start frequency, slope, idle, ramp and settle times) and emits frame and chirp timing strobes.
Simulated. The RTL is lint clean and passes its self-checking testbench against a reference model in simulation. It has not been run on an FPGA board or in silicon.
