It’s time to do a series on logic including things such as programmable logic, state machines, and the lesser known demons such as switching hazards. It is best to start at the beginning &#82… ...

If CS_ is not low (active), the FPGA must assume that another peripheral device is being read or written and ignore all other 8051 signals. Finally, we provide an output signal from the FPGA that will ...

I recently received an email from consultant David Wyland of the Wyland Group. Dave had been perusing my “FPGA Architectures From A to Z” articles (Part 1 and Part 2), in which one of the topics is ...

With the basic logic gates (NAND, NOR, NOT etc.) we can build a simple adder to multiplier to complete processor. If we can connect these logic elements inside a chip the way we want using a software ...

Logic synthesis tools also allows for technology independent designs. Logic synthesis technology was commercialized around 2004, and since then it’s been part of the standard EDA tool chain for ASICs ...

When [iliasam] needed an Ethernet connection, he decided to see how much of the network interface he could put in the FPGA logic. Turns out that for 10 Base-T, he managed to get quite a bit inside … ...

The paper describes a method of finding optimal sets of logic gates for the development of field-programmable gate array (FPGA). The proposed method is based on the Pareto optimality search procedure.

The timing diagram editors can also extract SDC timing constraints from timing waveforms created by simulations or captured from hardware with a logic analyzer. In this methodology, the user imports ...
