LC4384C-75FTN256C Generic Logic Block

The Generic Logic Block (GLB) of the LC4384C-75FTN256C processes logic operations using a flexible and efficient design. It receives 36 inputs from the Global Routing Pool (GRP), which are combined using an AND Array to form 83 product terms. These product terms are basic logic combinations that are managed by a Logic Allocator. The Logic Allocator distributes these product terms to 16 Macrocells, which are the main processing units. These macrocells perform logic functions, including combinational and sequential operations. They are synchronized by a Clock Generator using four clock signals (CLK0 to CLK3), allowing precise timing control. Each macrocell can send its output back to the GRP or to the Output Routing Pool (ORP) for further processing. They support feedback for implementing complex state machines and sequential circuits. The GLB’s design is highly flexible, enabling complex logic functions with efficient routing and timing control, suitable for advanced digital designs.

The macrocell supports multiple clock sources such as Block Clocks (CLK0 to CLK3), PT Clock, and Shared PT Clock, with a Clock Multiplexer selecting the appropriate source for precise timing control. At its core, a D/T/L Flip-Flop operates in different modes, D (Data), T (Toggle), or L (Latch) and features a Clock Enable (CE) input for conditional clocking. Outputs from the macrocell can be routed to the Output Routing Pool (ORP) for external connections or the Global Routing Pool (GRP) for internal feedback, allowing for complex logic functions and efficient signal routing. A Delay Element ensures proper timing and signal alignment, making the macrocell highly adaptable for advanced digital designs.
