SystemVerilog与Verilog描述状态机_FSM_之比较
As technology scales, the protection of Finite State Machines' (FSMs) states against single event upset and multiple bit upsets becomes more difficult. In this paper, a self-checking approach to enhance the SEU/MBUs immunity of FSMs' states by replicating One-Hot code times for s...

The verilog code below is a FSM I designed . I find this FSM can run correctly and jump between different states at first , but after running several seconds it will fall into a fixed state(state=0, state2=0 or state=7,state2=4) and never come out again. According to the logic...
Based on the notes from Lecture 5, implement this state machine in SystemVerilog to drive the neopixel bar and cycle through the F1 light sequence. You should use the switch on the rotary switch with the vbdFlag() function (in mode 1) to drive the en signal as shown below: Write the ...
