The guys over at hackshed have been busy. [Carl] is making programmable logic design easy with. Programmable logic devices are one of the most versatile hardware building blocks available to hackers.
Fundamentals of CPLD Design. CPLD Software Options. The Xilinx In-System Programming (ISP) software. Lab 2: Constraints for CPLDs. How To Program A Lattice Cpld. Our Programmers are designed to work at the fastest speeds possible by leveraging our flexible hardware and software architecture. The Quartus II software can be used to compile CPLD designs. Programming file from your CPLD design. Altera Design Flow for Lattice Semiconductor.
They also can have a steep learning curve. Cheap (FPGA) are plentiful, but can have intricate power requirements. Most modern programmable logic designs are created in a (HDL) such as. Now you’ve got a new type of device, a new language, an entirely new programming paradigm, and a complex IDE to learn all at once. It’s no wonder FPGAs have sent more than one beginner running for the hills.
The tutorial cuts the learning curve down in several ways. [Carl] is using (CPLD). At the 40,000 foot level, CPLDs and FPGAs do the same thing – they act as re-configurable logic. FPGAs generally do not store their configuration – it has to be loaded from an external FLASH, EEPROM, or connected processor. CPLDs do store their configuration, so they’re ready as soon as they power up. As a general rule, FPGAs contain more configurable logic than CPLDs. This allows for larger designs to be instantiated with FPGAs.
Don’t knock CPLDs though. CPLDs have plenty of room for big designs, like. [Carl] also is designing with schematic capture in his tutorial. With the schematic capture method, digital logic schematics are drawn just as they would be in Eagle or KiCad. Download Hdclone Enterprise Edition Full. This is generally considered an “old school” method of design capture.
A few lines of VHDL or Verilog code can replace some rather complex schematics. [Carl’s] simple designs don’t need that sort of power though. Going the schematic capture route eliminates the need to learn VHDL or Verilog. [Carl’s] tutorial starts with installing Altera’s Quartus II software.
He then takes the student through the “hardware hello world” – blinking an LED. By the time the tutorial is done, the user will learn how to create a 4 bit adder and a 4 bit subtractor.
With all that under your belt, you’re ready to jump into big designs –. [Image via ] Posted in, Tagged,,,,, Post navigation.
Thanks for the constructive criticism Alan. We haven’t released the guide as PDF at the minute as it’s a work in progress. If we receive enough requests for a downloadable version, we may look into it. As for the board, we’re currently working on another article which discusses using an official Altera board which comes with support. The “Cheap LC tech” board really is that, cheap, no support, no info.
We did the best we could with what we had available. I’ll bear your comments in mind for our next part of the guide.
Other than that, I hope these guides were of some use to someone.
