PLD design flow context In programmable logic device (PLD) development environments, “schematic capture” refers to creating a gate-level or block-level circuit diagram on screen and then using vendor tools to synthesize, map, and route that design onto the target device. Evaluate the statement: Schematic capture is a process performed by PLD software.

Introduction / Context: Schematic capture is one of the two classic front-end entry methods for programmable logic device (PLD) and field-programmable gate array (FPGA) projects, the other being hardware description languages such as VHDL or Verilog. In a schematic-based flow, the engineer draws logic symbols and interconnects to describe the intended hardware, and then lets the vendor software process that description into a configured device.

Given Data / Assumptions:

• The statement to evaluate is: “Schematic capture is a process performed by PLD software.”
• Typical vendor suites (for example, from Altera/Intel or Xilinx/AMD) include editors, synthesizers, mappers, placers, routers, and device programmers.
• Schematic capture produces a netlist that is consumable by downstream PLD tools.

Concept / Approach: The question probes your understanding of the PLD toolchain. Schematic capture is indeed a software-based activity where the design is captured graphically and then compiled by the PLD software. The output from capture is not sufficient by itself; it must be synthesized (if needed), fitted to device resources, and routed, all within the same tool suite.

Step-by-Step Solution:

Verification / Alternative check: Open any vendor IDE and select “Schematic” or “Block Diagram/Schematic File” to draw the logic; observe that subsequent steps (analysis, synthesis, fitting) are run by the same PLD tool.

Why Other Options Are Wrong: “Incorrect” would imply schematic capture is not part of PLD software, which contradicts standard flows where capture, synthesis, and implementation are integrated.

Common Pitfalls: Assuming schematic capture is obsolete. While HDL dominates, many vendors still support schematic entry for small systems, glue logic, or teaching.

Final Answer: Correct
