What Is the XCV100E-6PQG240C?

The XCV100E-6PQG240C belongs to Xilinx’s Virtex-E series — an evolutionary advancement over the original Virtex family. Built on a 6-layer metal, 0.18 µm CMOS process, the Virtex-E line was engineered for superior place-and-route efficiency. The “E” suffix denotes the enhanced generation, while the part number breaks down as follows:

XCV100E-6PQG240C Architecture Overview

## CLB and Slice Architecture

The XCV100E-6PQG240C features a CLB-based (Configurable Logic Block) architecture that forms the backbone of its programmable logic capability. Each CLB contains four slices, and each slice includes two 4-input look-up tables (LUTs), two flip-flops, and dedicated carry logic. This architecture enables efficient implementation of combinational and sequential logic, arithmetic operations, and small distributed RAM functions.

## SelectRAM and Block RAM

The device supports two forms of on-chip memory. Distributed SelectRAM is embedded within the CLB fabric, allowing flexible memory allocation without consuming block RAM resources. The dedicated 10 Kbits of Block RAM provides synchronous, dual-port memory suitable for FIFOs, buffers, and lookup tables in signal processing applications.

## SelectI/O Technology

All I/O blocks (IOBs) in the XCV100E-6PQG240C support Xilinx SelectI/O technology, enabling compatibility with a wide range of I/O standards. Each IOB can be independently configured for voltage levels between 1.5 V and 3.3 V. Supported standards include:

## Delay-Locked Loops (DLL)

Four on-chip DLLs provide clock management capabilities including clock deskewing, frequency synthesis, and phase shifting. These enable the XCV100E-6PQG240C to support zero-hold-time designs and reduce clock distribution skew across the FPGA fabric — critical for high-speed synchronous designs.

## IEEE 1149.1 Boundary Scan (JTAG)

The XCV100E-6PQG240C fully supports IEEE 1149.1 JTAG boundary scan for board-level testing and in-system programming. This simplifies PCB debug and allows configuration via JTAG without additional programming hardware.

XCV100E-6PQG240C Configuration Modes

The Virtex-E FPGA supports multiple configuration modes to suit different system designs:

Configuration data is stored in external non-volatile memory (such as Xilinx XCF PROM series), and the device loads its bitstream on power-up or on demand via JTAG.

Ordering Information & Part Number Variants

The XCV100E is available in multiple speed grades and packages. The table below shows the most common variants:

Note: The XCV100E-6PQG240C is Not Recommended for New Designs (NRND). Xilinx has designated this part as a legacy product. Engineers starting new projects are encouraged to evaluate modern Xilinx families such as Artix-7, Spartan-7, or Kintex-7 for new development.

Design Tools & Software Support

## Xilinx ISE Design Suite

The XCV100E-6PQG240C is supported by the Xilinx ISE Design Suite, specifically the legacy ISE version. ISE provides:

• HDL synthesis (VHDL and Verilog)
• Place and route implementation
• Timing analysis and constraint management
• Bitstream generation and download

The XCV100E is not supported in Xilinx Vivado Design Suite, which targets 7-Series and newer devices. Users must use ISE for design implementation.

## Simulation and Verification

Standard third-party simulators including ModelSim, Active-HDL, and Synopsys VCS are compatible with Xilinx Virtex-E simulation models. EDIF (Electronic Design Interchange Format) netlist support allows seamless integration with most EDA toolchains.

PCB Design Considerations for the XCV100E-6PQG240C

## Decoupling and Power Supply

Proper power supply decoupling is essential for reliable FPGA operation. The 1.8 V VCCINT rail requires low-ESR capacitors placed as close to the power pins as possible. A typical decoupling strategy includes:

• 100 nF ceramic capacitors at each VCC pin
• 10 µF bulk capacitors per power domain
• Dedicated power planes for VCCINT and VCCO

## Signal Integrity at High Speeds

At the maximum 357 MHz operating frequency, signal integrity becomes a key design concern. Engineers should apply controlled impedance routing (typically 50 Ω for single-ended), minimize stub lengths, and use series termination resistors on high-speed outputs where appropriate.

## Thermal Management

The XCV100E-6PQG240C in the PQFP package operates within the commercial temperature range (0°C to +85°C junction temperature). In high-power dissipation scenarios, a small heatsink or adequate PCB copper pour beneath the package can help maintain safe operating temperatures.

Frequently Asked Questions

## Is the XCV100E-6PQG240C still in production?

The XCV100E-6PQG240C is designated Not Recommended for New Designs (NRND) by AMD/Xilinx. While it may still be available through authorized distributors and the secondary market, production quantities are limited. It remains a viable option for legacy system repair and replacement.

## What is the difference between XCV100E-6PQG240C and XCV100E-6PQ240C?

The PQG variant indicates a Green/RoHS-compliant package using halogen-free materials and lead-free solder finish. The standard PQ variant uses a conventional tin-lead finish. The electrical and functional performance is identical between both.

## Can the XCV100E-6PQG240C be programmed in-circuit?

Yes. The device supports in-system configuration via JTAG (IEEE 1149.1) or through external serial/parallel PROM. JTAG programming is the most convenient method for development and field updates.

## What replaces the XCV100E-6PQG240C for new designs?

For new designs requiring similar logic capacity, Xilinx (AMD) recommends considering the Spartan-7 (XC7S15/XC7S25) or Artix-7 (XC7A12T/XC7A25T) families. These newer devices offer significantly more resources, higher performance, lower power consumption, and full Vivado tool support.
