FLEX10K logic element (LE) connectivity Evaluate the claim: “In the FLEX10K device, the logic element can produce two outputs to drive local (LAB) and global (fast-track) interconnects on the chip.”

Introduction / Context:
Altera’s FLEX10K family organizes logic into logic elements (LEs) inside logic array blocks (LABs). Understanding how an LE’s output is distributed to the interconnect fabric is crucial for timing and routing expectations.

Given Data / Assumptions:

• LEs produce a single logical output (from a LUT/combiner with optional register).
• Interconnect networks include local LAB routing and chip-level fast interconnect (often called FastTrack or global lines).
• Routing resources tap LE outputs and distribute them; LEs do not “generate” multiple distinct output pins.

Concept / Approach:
The statement suggests two separate output drivers per LE explicitly driving both local and global networks. In practice, an LE has one primary output that is made available to the routing fabric. The switch matrix can connect that output to local or higher-level interconnect as needed; this does not mean the LE itself produces two independent output signals.

Step-by-Step Solution:

Verification / Alternative check:
Vendor block diagrams show one LE output feeding a LAB interconnect; from there, switch matrices can drive wider networks, but the LE count of outputs remains one.

Why Other Options Are Wrong:
Labeling it “Correct” would conflate routing destinations with the number of LE output sources.

Common Pitfalls:
Mistaking routing flexibility for multiple physical outputs; assuming a “copy” on fast lines implies a separate LE driver.

Final Answer:
Incorrect
