App note: Clearing Xilinx FPGA configuration to allow boundary scan testing

Sunday, July 23rd, 2017

Another application note from XJTAG on preparing Xilinx FPGA for proper boundary scan testing. Link here When Xilinx FPGAs are configured it can restrict the boundary scan access to some signals on the device. One work-around for this problem is to configure the FPGA with a ‘blank’ image that closely...

How do I FPGA?

Friday, March 4th, 2016

TC-Engineering writes: I’ve been thinking about building stuff with FPGA’s for a while, and usually get turned away because FPGA’s are considerably harder to implement than microcontrollers since they have no on-chip memory. It is necessary to re-program the gates every time they power up, which requires an external flash...

App note: Implementing a TMDS video interface in the Spartan-6 FPGA

Saturday, June 20th, 2015

Implementing a TMDS video interface in the Spartan-6 FPGA, an app note here (PDF!) from Xilinx: The DVI and HDMI protocols use TMDS at the physical layer. The TMDS throughput is a function of the serial data rate of the video screen mode being transmitted. This in turn determines the FPGA speed grade...

Who says BGA packages are hard to solder

Wednesday, October 24th, 2012

Here is proof that soldering BGA's is not that hard. Check out this Mandelbrot zoom fractal engine with a PSP display project (machine translation). The FPGA in a ball grid array package is soldered dead bug style. Now that's skill. Via the forum, and Hack a Day.
