Hardware description languages (HDLs) are a category of programming languages that target digital hardware design. These languages provides special features to design sequential logic( the system evolve over time represented by a clock) or combinational logic (the system output is a direct function of its input). While these language have proved to be efficient to design hardware, they often lack the tool support (editors are far behind what you can get to edit C/java/etc) and the syntax can be ...
Abstract: This ’blog describes using a ValentF(x) LOGI-EDU board to make a 4-digit BCD (binary-coded decimal) counter using LOGI-EDU’s 4-digit seven-segment LED module.  I used both LOGI-Pi and LOGI-Bone FPGA boards to implement the BCD counter logic.   Disclaimer: This ’blog is distributed in the hope that it will be useful, but WITHOUT ANY WARRANTY.  Incorrect board connections and/or an incorrect FPGA bitstream could cause damage to an FPGA and/or its connecte ...
Introduction   In a previous blog post ValentF(x) gave an explanation of what FPGAs (field programmable gate arrays) are and how they are a very valuable resource when designing electronics systems.  The article went on to describe the major differences in the way FPGAs operate from CPU/MCU technology.  Finally, it was highlighted that FPGAs, especially when used in conjunction with CPU technology, are a powerful tool with both having their own respective strong points in how th ...
Abstract:  This ’blog describes my first experiments using a ValentF(x) LOGI-Pi FPGA board.  After a short overview of LOGI-Pi and its Xilinx Spartan-6 FPGA, we show how to download two examples.  The first is a pre-tested LED demo from ValentF(x) and the second is created from Verilog source code using Xilinx tools.   Disclaimer: This ’blog is distributed in the hope that it will be useful, but WITHOUT ANY WARRANTY.  Incorrect board connections and/or an inc ...
