2-bit Counter — Bluespec-systemverilog Code
A simple 2-bit synchronous counter using BSV rules.
module mkCounter2Bit(Bit#(2) count);
Reg#(Bit#(2)) cnt <- mkReg(0);
rule increment;
cnt <= cnt + 1;
count <= cnt;
endrule
endmoduleBluespec-systemverilog Language Guide
Bluespec SystemVerilog (BSV) is a high-level hardware description language (HDL) for designing complex digital systems. It extends SystemVerilog with a rule-based programming model, enabling modular, correct-by-construction hardware design.
Primary Use Cases
- ▸Designing FPGA-based digital systems
- ▸Building complex ASIC hardware components
- ▸Rapid prototyping of hardware modules
- ▸Hardware/software co-design experiments
- ▸Teaching hardware design and formal verification concepts
Notable Features
- ▸Rule-based execution for concurrent hardware actions
- ▸Strong type system and high-level abstractions
- ▸Supports parameterized and modular hardware components
- ▸Integration with simulators and formal verification tools
- ▸Automatic scheduling of hardware rules
Origin & Creator
BSV was developed at Bluespec Inc., building on research from MIT in the mid-2000s, as a way to improve productivity in hardware design using a high-level, rule-based language.
Industrial Note
BSV is highly specialized for digital system design in FPGAs and ASICs, particularly in applications requiring correctness, concurrency, and high-level hardware modeling.
