Xilinx FPGA Design Tools for Linux
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
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.

Until recently, IBM’s Power Platform was looked upon as being the system that hosted IBM’s flavor of UNIX and proprietary operating system called IBM i. These servers often are found in medium-size businesses running ERP, CRM and financials for on-premise customers. By enabling the Power platform to run the Linux OS, IBM now has positioned Power to be the platform of choice for those already running Linux that are facing scalability issues, especially customers looking at analytics, big data or cloud computing.
￼Running Linux on IBM’s Power hardware offers some obvious benefits, including improved processing speed and memory bandwidth, inherent security, and simpler deployment and management. But if you look beyond the impressive architecture, you’ll also find an open ecosystem that has given rise to a strong, innovative community, as well as an inventory of system and network management applications that really help leverage the benefits offered by running Linux on Power.Get the Guide
