As most hardware engineers, I started off my computer science career by learning a sequential programming language. The first language I learned at the University of Oslo was Java. While it’s not considered to be the most exciting language today, at the time, Java was at the pinnacle of its popularity. The engineers who built…
The VHDL Analysis and Standardization Group (VASG), has been working for quite some time on finishing the draft for the upcoming VHDL-2019 revision of the language. The ballot has been held, and a list of approved changes has emerged. What’s left before this becomes the latest revision of the VHDL language is for the draft…
The linked list is a dynamic data structure. A linked list can be used when the total number of elements is not known in advance. It grows and shrinks in memory, relative to the number of items it contains. Linked lists are most conveniently implemented using classes in an object-oriented programming language. VHDL has some…
Delta cycles are non-time-consuming timesteps used by VHDL simulators for modeling events during execution of VHDL code. They are events that happen in zero simulation time after a preceding event. VHDL is a parallel programming language, while computers and CPUs work in a sequential manner. When a normal programming language is run, the CPU executes…
Most of us stick to a certain way of writing a state machine. Perhaps you type out the construct that you are most familiar with without giving much thought to the alternatives. Depending on the method that you were taught when learning VHDL, you may prefer one method to another. Over the years, I have…
