It’s a more elegant alternative to an If-Then-Elsif-Else statement with multiple Elsif’s. In VHDL we can do the same by using the ‘when others’ where ‘others’ means anything else not defined above. This makes certain that all combinations are tested and accounted for. Later on we will see that this can make a significant difference to what logic is generated. For now, always use the ‘when others’ clause. So, VHDL is a strong typed language, and the condition you have given for when can't resolve because bit_cond_true is a std_logic, and (my_array /= X"00000") resolves to a boolean. Therefore you get the ModelSim error No feasible entries for infix operator "and".

In a previous post in this series, we looked at the way we use the VHDL entity, architecture and library keywords. These are important concepts which provide structure to our code and allow us to define the inputs VHDL stands for very high-speed integrated circuit hardware description language. It is a programming language used to model a digital system by dataflow, behavioral and structural style of modeling. This language was first introduced in 1981 for the department of Defense (DoD) under the VHSIC program. Describing a Design Case Statement - VHDL Example. The VHDL Case Statement works exactly the way that a switch statement in C works.

How to use a Case-When statement in VHDL Tuesday, Sep 12th, 2017 The Case-When statement will cause the program to take one out of multiple different paths, depending on the value of a signal, variable, or expression. It’s a more elegant alternative to an If-Then-Elsif-Else statement with multiple Elsif’s.

With an increase in the scale of our designs, smart implementation of these operators can help us make our program efficient and save on resources. VHDL nackdelar? Svårt att lära sig?
