Functional Overview: XC4000XLA Architecture
CLB Structure and Logic Capacity
The XC4062XLA-09HQ240I is built around Xilinx’s mature CLB (Configurable Logic Block) architecture. Each CLB contains:
- Two 4-input function generators (F and G) for combinatorial logic
- One 3-input function generator (H) for additional flexibility
- Two flip-flops or latches for sequential logic storage
- Support for functions of up to 9 input variables (e.g., parity check, identity comparison)
- Distributed RAM capability within CLBs for on-chip memory
I/O Block (IOB) Features
The XC4062XLA-09HQ240I’s IOB provides flexible I/O interfacing:
- Input and output independently configurable
- Fast Capture latch on inputs for high-speed data capture
- CMOS or TTL-compatible output drivers (globally configurable)
- Programmable pull-up or pull-down resistors on all I/Os
- Slew-rate control per output for EMI management
Routing and Interconnect
- Dense multi-layer metal interconnect fabric
- Short-distance (local), medium-distance (long lines), and global routing resources
- Global clock distribution network supporting high-fanout clocks up to 238 MHz
- Global Set/Reset capability for synchronous design initialization
