Cheat Sheet
- Module and Port Declaration Best Practices -
Whether you're prepping for your verilog exam or a digital design quiz, clear module definitions reduce debugging time: e.g., module adder(input [3:0] a, b, output [4:0] sum);. Always match port widths and directions to synthesis tool expectations. A mnemonic like "I-O-M" (Inputs, Outputs, Module) helps remember port ordering from most to least significant.
- Always Blocks and Sensitivity Lists -
In combinational logic, use always @(*) to ensure signals update correctly and avoid simulation mismatches; omitting a signal from the list can introduce unintended latches. For sequential logic, always @(posedge clk or posedge rst) captures clocked behavior - explicit reset handling is recommended by the IEEE 1364 standard. University courses like MIT's 6.111 highlight common pitfalls in always-block usage.
- Blocking vs Nonblocking Assignment Nuances -
Blocking ("=") assignments execute immediately and suit combinational code, while nonblocking ("<=") update registers at the end of a timestep in sequential logic. Mixing them incorrectly creates race conditions - remember "<= for Flip-Flops, = for Functions." Synthesis guides from Synopsys and Xilinx stress this rule to prevent unintended hardware latches.
- Timing Constraints: Setup, Hold, and Clock Domains -
Setup time (tSU) and hold time (tH) define valid sampling windows; violating them leads to metastability. Use SDC constraints (set_input_delay, set_output_delay) to specify real-world path delays, as detailed in Intel/Altera whitepapers. In multi-clock designs, clear clock naming (clk, clk_2x) avoids domain-crossing hazards during your verilog hdl test.
- Synthesis-Friendly Coding Styles -
Stick to synthesizable constructs: avoid #delays, prefer case statements over nested if-else for priority encoding, and use generate blocks for scalable arrays. Tools like Cadence NC-SIM and Xilinx Vivado flag unsupported patterns - consult their synthesis manuals to align your code with real-world HDL design questions. A simple rule: write what you want in hardware, not software.
