XCV1000E-7BG728C Architecture Overview
Configurable Logic Blocks (CLBs)
The Virtex-E CLB architecture organizes logic into slices, each containing two 4-input Look-Up Tables (LUTs) and two flip-flops. Each CLB contains 2 slices (4 LUTs total). The CLBs support:
- Implementation of any 4-input Boolean function
- Combination of two LUTs for 5- or 6-input functions
- Synchronous 16×1-bit or 32×1-bit distributed RAM
- Shift registers for data buffering
- F5/F6 multiplexers for wide logic functions
BlockRAM (Dual-Port 18Kb)
The XCV1000E-7BG728C includes 28 dual-port BlockRAM blocks, each 18 Kb. These support:
- Independent read/write port widths (1 to 18 bits per port)
- Synchronous read and write operations
- True dual-port mode (simultaneous read/write on both ports)
- Configurable as ROM or RAM
Clock Management
The device integrates Delay-Locked Loop (DLL) circuits for precise clock management:
- Up to 4 global clock networks
- DLL-based clock deskew and multiplication
- Low-skew global routing trees
- Support for external clock synchronization
I/O Block (IOB) Features
Each I/O pin is supported by a programmable IOB that includes:
- Input flip-flop / latch
- Output flip-flop with 3-state control
- Programmable drive strength (2 mA to 24 mA)
- Slew-rate control (fast / slow)
- Programmable pull-up/pull-down resistors
- LVDS and differential signaling support
