Historical note on PLD adoption and PAL devices Evaluate the statement: “PLDs did not gain widespread acceptance until the mid-1980s, when a device called a PAL was introduced.”

Introduction / Context:
Programmable logic adoption followed the introduction of key device families. PAL (Programmable Array Logic) devices were pivotal in popularizing PLDs, but the timeline matters when evaluating historical claims.

Given Data / Assumptions:

• PAL devices appeared commercially in the late 1970s and were used widely in the early 1980s.
• By the mid-1980s, multiple PLD families (PAL, GAL, early CPLDs) were already well established.
• “Introduced” implies first appearance, not long-after adoption.

Concept / Approach:
The statement connects widespread acceptance specifically to the mid-1980s and suggests PAL was introduced then. In reality, PALs were introduced earlier and helped seed adoption before the mid-1980s. Therefore, tying PAL’s introduction to mid-1980s is inaccurate.

Step-by-Step Solution:

Verification / Alternative check:
Timelines in standard digital design texts show PALs catalyzed PLD usage in the early 1980s, with GALs and CPLDs following.

Why Other Options Are Wrong:
Marking “Correct” would accept an incorrect introduction date linkage and over-narrow the adoption window.

Common Pitfalls:
Blurring “first introduced” with “most widely used.” Adoption is gradual and began earlier than mid-1980s for PALs.

Final Answer:
Incorrect
