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.

Difficulty: Easy

Correct Answer: Correct

Explanation:


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:

Recognize that “schematic capture” names the front-end drawing process.Note that the process is executed within EDA/PLD software on a computer, not manually on paper.Understand that the captured schematic becomes a netlist for compilation, fitting, and bitstream generation.Conclude that the statement is accurate within normal PLD workflows.


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Assuming schematic capture is obsolete.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
