What are the Features and Applications of the Xilinx Spartan 6 FPGAs?

Introduction to FPGAs

FPGA (Field Programmable Gate Array) is a type of programmable logic device that can be configured or programmed to desired functionality after manufacturing. This provides flexibility to update or modify the logic, making FPGAs suitable for prototyping and product development.

Some key capabilities of FPGAs:

• Contains programmable logic blocks and interconnects
• Can implement custom digital circuits by programming logic gates and connections
• Reconfigurable even after deployment in the field
• Used for DSP, software-defined radio, image processing, etc.
• Suitable for rapid prototyping and iterative design

FPGAs contain configurable logic blocks, I/O pads, block RAMs, DSP slices, clocking resources, and routing interconnects. The FPGA is programmed by loading configuration data into static memory cells that control the logic blocks and connections.

There are many different FPGA products available from vendors like Xilinx, Altera, Lattice, Microsemi, etc. tailored for applications ranging from small glue logic to high-performance processing.

Spartan-6 Architecture

Spartan-6 FPGAs utilize a flexible, regular architecture to enable scalability across the product families. Understanding the device architecture helps make effective use of the resources.

Configurable Logic Blocks

The main configurable logic blocks are 6-input look-up table (LUT) based slices:

• Each slice contains four 6-input LUTs and eight flip-flops
• Combinational and synchronous sequential logic built from LUTs
• Wide multiplexers, arithmetic, and shift elements

Slices are grouped into configurable logic blocks (CLBs). Each CLB contains two slices, for up to eight LUTs and 16 flip-flops.

Routing and Interconnect

A hierarchical routing architecture connects the CLBs, I/Os, and other blocks:

• Direct connections between adjacent logic resources
• Unidirectional routing switches between rows and columns
• Long lines for low-skew routing across the device

Electrical Characteristics of the Xilinx Spartan 6 FPGAs

The Xilinx Spartan 6 FPGAs come in different speed grades. Of all the speed grades, we have -3 having the greatest performance. Also, the AC and DC electrical parameters of the Spartan-6Q FPGAs (Defense-grade) and the XA Spartan-6 FPGAs (Automotive) devices are usually equal to the specifications except areas where noted.

Furthermore, industrial devices with a speed grade of -2 have similar timing characteristics as commercial devices having a speed grade of -2.

Also, the speed grades of -3Q and -2Q are for the expanded range of temperature. Furthermore, the characteristics of timing are also equivalent to that revealed for speed grades of -3 and -2 for the defense-grade and automotive devices.

In addition, the AC and DC characteristics of the Spartan-6 FPGA are indicated for expanded (Q), industrial (I), and   commercial (C) temperature ranges. Moreover, just selected speed devices and/or speed grades may be available for the expanded or industrial temperature ranges for the defense-grade and automotive devices.

Furthermore, device names’ references involve the variations available for a specific part number. Let’s choose LX75 for example. Also, this could mean XQ6SLX75, XA6SLX75, or XC6SLX75. A speed grade of -3N for the Xilinx Spartan 6 FPGA family implies devices, which don’t support the functionality of the MCB.

Also, all the specifications of the junction temperature and supply voltage represent any worst-case condition. Furthermore, the inclusion of the parameters is great for typical applications and popular designs and typical applications.

Xilinx Spartan 6 FPGA Switching Characteristics

The specification of the Xilinx Spartan 6 FPGAs’ switching characteristics is on the basis of per-speed-grade. Furthermore, you can design them as Preliminary, Advance, or Production. You can define each of these designations as follows:

Preliminary

The basis of these specifications is on total or complete ES silicon characterization. In addition, speed grades and devices having this designation will help you know better of the production silicon’s expected performance. Moreover, in contrast to Advance data, the chance of having delays in under-reporting is reduced greatly in contrast to the Advance data.

Advance

For advance, the basis of the specifications is on simulations alone. Also, they are available immediately after the freezing of the specifications of the device design. Moreover, though speed grades having this designation are usually seen as conservative and relatively stable, it is possible for some underreporting to happen.

Production

For production, the release of these specifications happens immediately enough silicon of a specific family member of a device has been shown to offer total correlation between devices and specifications over many production lots.

Here, delays are not underreported. Furthermore, anytime there is any subsequent change, the information gets to the customers. Also, grades with the slowest speed transform to Production even before grades with faster speed.

In addition, all the specifications always represent junction temperature and supply voltage worst-case conditions. However, the production of individual members of the family happen at different periods and times, migrating between different categories hinges totally on the result of the process of fabrication for all the individual devices

Also, the speed grade -1L involves the Spartan-6 FPGA devices with lower power. Furthermore, the speed grade of -3N involves the Spartan-6 FPGA devices, which doesn’t support the functionality of the MCB.

Switching Characteristics Testing

Importantly, for switching characteristics testing, all the devices usually undergo a functional test 100%. Also, you derive the parameters for internal timing from the measurement of the patterns for the internal test. Also, you can find the representative values below.

Furthermore, in order to get a worst-case, more precise, and more specific data, make use of the values that the timing analyzer gives. Also, unless it is otherwise stated, these values work for all Spartan 6 FPGA devices.

Production ISE Software and Silicon Status

Furthermore, there are cases whereby the release of a particular speed grade and family member to production happens before the release of a speed specification with the right label (Production, Preliminary, and Advance). Also, the correction of all labeling discrepancies occurs in all subsequent releases for speed specification.
