Xilinx FPGA Design Tools for Linux

Linux is making big moves into electronic design automation. Michael introduces a way to implement your designs in reconfigurable hardware.
Linux and Interoperability

The tools also can be used on the command line, instead of with the GUI. Once the Xilinx binaries are on your Linux $PATH, you can drive them with batch mode scripts, programs and makefiles. If you want to run these commands from the shell, you can crib from the command log, produced by the Project Navigator, and improvise from there. For example, these commands can be modified to add shell variables. For the design created in this article, the generated command log text looks like:

xst -intstyle ise -ifn __projnav/mpy16.xst \
-ofn mpy16.syr
ngdbuild -intstyle ise \
-dd /home/mab/VERILOG/MPY-TEST/_ngo -i  \
-p xc2vp7-fg456-6 mpy16.ngc mpy16.ngd
map -intstyle ise -p xc2vp7-fg456-6 -cm area \
-pr b -k 4 -c 100 -tx off \
-o mpy16_map.ncd mpy16.ngd mpy16.pcf
par -w -intstyle ise -ol std -t 1 mpy16_map.ncd \
mpy16.ncd mpy16.pcf
trce -intstyle ise -e 3 -l 3 -xml mpy16 mpy16.ncd \
-o mpy16.twr mpy16.pcf
bitgen -intstyle ise -f mpy16.ut mpy16.ncd

Conclusion

We have introduced FPGAs in the context of modern semiconductor technology, have described how software and hardware lines are blurring and have taken a quick tour of the ISE 6.1i FPGA implementation tools on Linux. You also can refer to the August 2002 issue of LJ (/article/6073), which first introduced the Xilinx ML300 development board and embedded Linux on the Virtex-II Pro FPGA.

Linux Management with Red Hat Satellite: Measuring Business Impact and ROI

Linux has become a key foundation for supporting today's rapidly growing IT environments. Linux is being used to deploy business applications and databases, trading on its reputation as a low-cost operating environment. For many IT organizations, Linux is a mainstay for deploying Web servers and has evolved from handling basic file, print, and utility workloads to running mission-critical applications and databases, physically, virtually, and in the cloud. As Linux grows in importance in terms of value to the business, managing Linux environments to high standards of service quality — availability, security, and performance — becomes an essential requirement for business success.

White Paper
Private PaaS for the Agile Enterprise

If you already use virtualized infrastructure, you are well on your way to leveraging the power of the cloud. Virtualization offers the promise of limitless resources, but how do you manage that scalability when your DevOps team doesn’t scale? In today’s hypercompetitive markets, fast results can make a difference between leading the pack vs. obsolescence. Organizations need more benefits from cloud computing than just raw resources. They need agility, flexibility, convenience, ROI, and control.

Stackato private Platform-as-a-Service technology from ActiveState extends your private cloud infrastructure by creating a private PaaS to provide on-demand availability, flexibility, control, and ultimately, faster time-to-market for your enterprise.
