Migrating Spartan-6 Designs to 7 Series & Beyond white paper

PublishTime：2022-05-26

Abstract–This white paper will outline the challenges and mitigation strategies which can beimplemented when migrating from a Xilinx Spartan-6 FPGA to a Xilinx 7 series device or beyond.
●Introduction
■The semiconductor shortage is having significant impacts on the supply chain, and this is especially true for older nodes such as the 45nm upon which the Spartan®-6 device is fabricated. Although there are still challenges with 7 series and UltraScale™/UltraScale+™ deliveries, I am informed that more modern nodes exhibit an improved long-term supply situation.
In this white paper, we are going to understand the differences between the Spartan-6 and 7 series architectures. We will also discuss how we can select the most appropriate migration device from the 7 series range along with how to migrate the tool chain from ISE® to Vivado®.This white paper will also examine how best to migrate a range of designs from pure RTL-based designs to those which contain a significant element of IP and softcore microcontrollers such as MicroBlaze™ within the programmable logic fabric.
First introduced in 2009, the Spartan-6 family is based on a 45 nm process and provides developers within the standard LX version 3.8K and 147K logic cells, up to 576 I/O, 180 DSP slices, and 268 18Kb block RAMS. The transceiver enabled LXT versions provides the logic resources of the LX family and provide up to eight GTP transceivers and 1 PCI Express end point.
Both the LX and LXT range of devices provide hard integrated memory controllers, which support DDR, DDR2, DDR3, and LPDDR with data rates up to 800 Mb/s.
Introduced in 2010, the 7 series consist of five families of devices including the Virtex®-7, Kintex®-7, Artix®-7, Zynq®-7000, and Spartan®-7. This range of families in the 7 series provides developers sufficient capacity, capability, and performance to migrate a Spartan-6 device but also enables significant opportunity for future product enhancement.
