XCV1000E-7FG680C Architecture Overview: Virtex-E Family Deep Dive

What Makes the Virtex-E Architecture Powerful?

The XCV1000E-7FG680C belongs to Xilinx’s Virtex-E family, which represents a major architectural evolution from the original Virtex platform. The Virtex-E family was engineered to maximize silicon efficiency, with optimizations made specifically for place-and-route performance on a state-of-the-art 0.18 µm CMOS process using 6 layers of metal interconnect. This enabled significantly higher logic density, faster routing, and lower power consumption compared to the prior 0.22 µm Virtex generation.

Configurable Logic Blocks (CLBs) and Logic Cells

The XCV1000E-7FG680C contains 6,144 Configurable Logic Blocks (CLBs), each comprising four slices. Each slice includes two 4-input Look-Up Tables (LUTs), flip-flops, carry logic, and dedicated arithmetic functions. This yields 27,648 logic cells total, supporting complex designs including state machines, arithmetic pipelines, and data path logic.

Block RAM Architecture

With 393,216 bits (384 Kb) of on-chip block RAM, the XCV1000E-7FG680C supports a wide range of memory-intensive applications. Block RAM can be configured as:

DLL (Delay-Locked Loop) Clock Management

The Virtex-E family integrates on-chip Delay-Locked Loop (DLL) circuits for superior clock distribution and management. DLLs eliminate clock skew, enable clock multiplication/division, and support phase shifting — critical for synchronous high-speed designs.

I/O Standards Support

The 512 user I/O pins of the XCV1000E-7FG680C support a rich set of programmable I/O standards, providing design flexibility when interfacing with external memory, buses, and peripherals:

XCV1000E-7FG680C Performance Characteristics

Speed Grade -7 Explained

The -7 speed grade designation indicates the performance tier of this FPGA variant. Within the XCV1000E family, the -7 grade achieves a maximum clock frequency of 400 MHz, making it one of the faster variants suited for time-critical logic functions. Higher speed grades (e.g., -8) may support up to 416 MHz, while slower grades (-6) are rated for 357 MHz.

Propagation Delays and Timing

The Virtex-E -7 speed grade provides competitive internal propagation delays for its generation:

Exact timing values should be obtained from the official Xilinx XCV1000E datasheet and confirmed with timing analysis tools.

Frequently Asked Questions About XCV1000E-7FG680C

Is the XCV1000E-7FG680C still in production?

No. The XCV1000E-7FG680C has been classified as obsolete by AMD Xilinx. It is not recommended for new designs. However, the part remains widely available through independent electronics distributors for legacy system maintenance and repair.

What is the difference between XCV1000E-7FG680C and XCV1000E-6FG680C?

The primary difference is the speed grade: the -7 version operates at up to 400 MHz, while the -6 version is rated for up to 357 MHz. All other specifications (logic cells, RAM, I/O count, package) remain identical.

What software do I need to program the XCV1000E-7FG680C?

Xilinx ISE Design Suite 14.7 is the recommended toolchain. Vivado does not support Virtex-E family devices. ISE 14.7 is the final version and includes the iMPACT programmer, XST synthesizer, and PAR (Place and Route) tools.

Can the XCV1000E-7FG680C be used in industrial temperature applications?

The “C” suffix indicates a commercial temperature grade (0°C to +85°C). For industrial temperature range (-40°C to +100°C), you would need the “I” suffix variant if available. Verify specifications before deploying in extended temperature environments.

What are the closest modern replacements for XCV1000E-7FG680C?

While there is no direct pin-compatible modern replacement, the Xilinx Virtex-5, Virtex-6, or Kintex-7 families offer far superior performance and density for new designs. Any migration will require schematic and PCB redesign due to different packages and architectures.
