RTL Finite State Machines in System Verilog

Explore the RTL FSM design pattern in SystemVerilog by defining states and encoding, writing next-state logic, and implementing transitions, then map Euclid's gcd algorithm to a finite state machine.

Design an RTL gcd finite state machine in SystemVerilog, using a handshaked IO interface with a and b inputs, o_valid and o_busy signals, and parameterized operand width.

Encode the five-state RTL finite state machine in SystemVerilog with an enumerated type, three-bit encoding, and an always_ff block using underscore w and r signals and a case statement.

Explore how the rtl finite state machine transitions from load to compare, subtract, swap, and result states via arcs, using underscore w/r signals, busy and done flags, and registered result.

Reuse the GCD RTL test bench to simulate the FSM, adjust width and timeout, diagnose a missing default next_state, and verify reset behavior in a dockerized environment.

Rerun the RTL simulation to verify gcd results and inspect waveforms for varied inputs. Display readable state names by printing ASCII-encoded state values with an always_comb mapping.

Synthesize the rtl finite state machine in SystemVerilog and verify the synthesis output with gate simulations, noting 58 cells, 17 flip flops, no latches, and the gcd_gates.csv results.

Measure latency by counting clock cycles from stimulus to result, using a record and operands class to track inputs, outputs, and max/min latency across 225 combinations.

Measure latency in rtl fsm by running a docker-based sim on mac, fix gcd dot csv syntax error, and verify 5 to 37 cycles with gtkwave on 10 ns clock.

Streamline the gcd rtl fsm by consolidating subtract, swap, and result into a compute state, reducing from three states to two and validating latency gains with rtl simulation.

Run the synthesis script to confirm success and the two-level max timing path. Observe 58-to-50 cell drop as state narrows to one bit, and verify latency with gait sim.

Explore explicitly coding a one-hot state register for a four-state rtl finite state machine, compare with binary encoding, and highlight when simpler next-state logic, faster performance, and lower power result.

Learn to implement a five-state gcd fsm in SystemVerilog using a one hot encoded state vector, with named parameters for each bit, one tick transitions, and ascii state display.

Simulate the rtl finite state machine in a Docker container, generate the simulation script with Ninja, verify latency matches the five-state baseline, and view the waveforms of the states.

Synthesize the RTL finite state machine and observe the max delay path remains two levels of logic, with the total cell count at 67, up from 58 with binary encoding.

Verify rtl finite state machine synthesis by running results on the synthesized netlist, confirm latency, inspect waves, set radix to decimal, and review gate netlist for parameter-defined o valid transitions.

Explore rtl finite state machines in SystemVerilog, from controlling data paths and link handshakes to applications in usb, pci express, and uart protocols.

Follow instructions to install docker on Windows using WSL2, including Ubuntu 20.04 from the Microsoft Store and verifying with PowerShell, then start Docker Desktop and confirm it runs.

Pull docker images from hub.docker.com to access Vivado 2024 tool set with docker pull command. Observe image sizes, including ~2 gb download and ~5.5 gb uncompressed XM dash synth image.

Run GUI inside a Docker container on Windows by installing an X server (x MinGW), disabling access control, and using docker run with -it, -e DISPLAY, -H, -V, and image.

Enter the Ubuntu container, run the test install.sh script, and simulate and synthesize a small design; visualize the clock waveform with Gtkwave.

EDA playground lets you simulate digital logic in a browser using remote commercial simulators. Load design and testbench, run with Aldec, view waveforms, and save your work.
