Is it better for me to check these conditions outside the state machine in seperate (parallel) processes since I am dealing with 16-bit vectors? courses:system_design:vhdl_language_and_syntax:sequential_statements:if If the number of bits G_N is going to become huge, the 2-way mux could, eventually, not implementable in your hardware. Resources Developer Site; Xilinx Wiki; Xilinx Github If-statements in VHDL: nested vs. multiple conditions, How Intuit democratizes AI development across teams through reusability. The if generate statement was extended in the VHDL-2008 standard so that it can use multiple branches. Lets have a look to the syntax of while loop, how it works. It's most basic use is for clocked processes. I want to understand how different constructs in VHDL code are synthesized in RTL. In VHDL, for loops are able to go away after synthesis. Unlike with a lot of VHDL statements, we must give a label to all generate statements which we write. Necessary cookies are absolutely essential for the website to function properly.
