In the Altera MAX7000S family, identify the two major on-chip structures that define logic clustering and interconnection resources.

Introduction / Context:
MAX-class CPLDs group macrocells into logic array blocks (LABs) and connect those LABs using a global interconnect. Knowing these architectural terms helps you reason about placement, timing, and resource usage.

Given Data / Assumptions:

• Target family: MAX7000S.
• We must pick the two key structures that represent logic clusters and the chip-wide interconnect fabric.

Concept / Approach:
In MAX7000S, macrocells are organized into LABs. LABs connect to each other and to I/O via the Programmable Interconnect Array (PIA). While LUTs dominate FPGA fabrics, CPLDs use product-term macrocells; thus “LUT” is not the primary resource in this CPLD family. FMUX is a vendor-specific multiplexer feature elsewhere; it is not a top-level architectural pair for MAX7000S.

Step-by-Step Solution:
Identify logic clustering → LAB.Identify global/inter-LAB routing → PIA.Select LAB and PIA as the two major structures.

Verification / Alternative check:
Family block diagrams label macrocells grouped into LABs with a PIA providing routing.

Why Other Options Are Wrong:
LUTs characterize FPGAs more than MAX CPLDs. FMUX is not the defining chip-level interconnect for MAX7000S. Pairings with LUTs therefore mischaracterize the architecture.

Common Pitfalls:
Assuming all programmable logic uses LUTs; overlooking that CPLDs implement sum-of-products macrocells instead.

Final Answer:
LAB, PIA
