HDL to PLD Flow — Naming the Translation Tool In a programmable logic design workflow, which special software tool translates hardware description language (HDL) code into the 1/0 configuration (e.g., a JEDEC or bitstream) that can be loaded into a PLD or FPGA?

Introduction / Context:Designing with PLDs and FPGAs involves writing HDL (VHDL/Verilog/SystemVerilog) and then converting that description into a device-specific configuration of logic elements and interconnects. The software that performs synthesis, fitting, placement, and routing ultimately emits the 1/0 pattern used to program the device.

Given Data / Assumptions:

• Target device is a PLD/FPGA.
• Input is HDL source.
• Output is a configuration file (e.g., JEDEC file, bitstream).

Concept / Approach:EDA vendors commonly refer to the overall translation toolchain as a “compiler.” Internally it runs synthesis (HDL to netlist), technology mapping, and place-and-route to produce a final programming file. While different phases have specific names, the umbrella term in tool GUIs and documentation is typically “compiler.”

Step-by-Step Solution:1) Parse HDL to build an abstract hardware model.2) Synthesize logic into a gate-level or LUT-level netlist.3) Map, place, and route into the device fabric.4) Generate the 1/0 configuration (JEDEC/bitstream) for programming.

Verification / Alternative check:Major toolchains (e.g., Quartus “Compiler”, Vivado “Synthesis/Implementation” runs) use similar terminology; user workflows often refer to “compiling” a design to produce a programming file.

Why Other Options Are Wrong:

• formatter.: Not a standard term in PLD/FPGA flows.
• programmable wiring.: Describes a concept, not a software tool.
• CPU.: Hardware processor, not the EDA software.

Common Pitfalls:Confusing individual phases (synthesis, fitter) with the name of the entire translation process; in many teaching contexts, “compiler” is the accepted high-level term.

Final Answer:compiler.
