Quartus uses ModelSim (Altera Edition) to perform simulation. ModelSim is even used for Vector Waveform files. ModelSim and Quartus are two entirely separate applications that loosely communicate with each other. You typically invoke ModelSim from Quartus via the Tools -> Run Simulation Tool -> RTL Simulation menu However, if you’ve every tried to run ModelSim… Continue reading Setting up Quartus to run ModelSim

For those with access to IEEE standards (many universities do), the VHDL standards can be found using this site:   https://ieeexplore.ieee.org/xpl/opacstd.jsp The VHDL standards are numbered 1076.x so narrow your search to include 1076. This will get you access to the definitive source.

I get questions about this a lot, so I thought I’d try and explain this. If we are to build an adder circuit from digital electronics, there is only one circuit which performs addition signed and unsigned adder circuits are identical The overflow and carry bits will be set or reset depending on the input… Continue reading Carry and Overflow are not the same thing!

For those using Mbed-os, and always wanted to work offline, this may be good news. Arm has recently released a public beta of Mbed Studio, their new IDE specifically for Mbed os. This can be downloaded and tested here – https://os.mbed.com/studio/ This includes the Arm v6 compiler and support for a wide range of boards. Mbed… Continue reading Mbed Studio Beta is now live
