Design flow terminology In a typical PLD/FPGA design flow—after design entry and functional/timing simulation—the final step in which the compiled design is implemented onto the target device is commonly called what?

Introduction / Context:
Digital design flows follow a consistent sequence: enter the design (schematic or HDL), synthesize/fit, simulate to verify behavior, and finally program the hardware. Accurately naming each step helps avoid confusion during lab work and documentation.

Given Data / Assumptions:

• “Compiling” generally includes synthesis, mapping, placement, and routing to produce a device image.
• “Simulation” verifies function and possibly timing before hardware programming.
• The concluding action is to transfer the bitstream/JED/POF file into the actual device.

Concept / Approach:
The industry uses several synonyms (programming, configuration, downloading). In PLD labs and many textbooks, “downloading” specifically refers to sending the compiled image to the device over JTAG or another programming interface so the device implements the intended logic.

Step-by-Step Solution:

Verification / Alternative check:
Vendor tools label this stage “Program Device,” “Download,” or “Configure Target.” Each describes the act of writing the compiled image to hardware.

Why Other Options Are Wrong:
“Compiling” precedes programming; it prepares the image. “Simulation” is a verification step, not implementation. “Design entry” is the very first step.

Common Pitfalls:
Using “compile” and “download” interchangeably. Compiling generates the file; downloading applies it to the chip.

Final Answer:
downloading
