Lattice Implements Risc-V Softcore on MachXO4

Lattice Semiconductor's MachXO4 FPGA is used in a step-by-step tutorial demonstrating how to create a Risc-V softcore using the Radiant toolchain and Propel System Builder. The guide covers workspace setup, peripheral selection (UART, GPIO), firmware compilation (riscv_sm_helloworld.mem), synthesis, place-and-route, and programming the LFMXO4-110-EVN evaluation board with its 10K-logic device. Practitioners gain end-to-end instructions to deploy and test embedded controllers.
