VHDL Variables: Is it combinational code inside a clocked process?

WebCAUSE: In a VHDL Design File at the specified location, you attempted to infer a register for the specified signal. However, you assigned a value to the signal on a clock edge, and then you assigned a value to the signal outside this clock edge (this second value assignment may be triggered by a different clock edge or by an asynchronous condition). WebApr 14, 2024 · 2.3 RTL Design Process. The RTL design process consists of several steps that guide the designer from the initial specifications to a fully verified and optimized digital circuit. These steps include RTL coding, synthesis, and verification. Each step plays a crucial role in ensuring a successful RTL design. The vast majority of VHDL designs uses clocked logic, also known as synchronous logic or sequential logic. A clocked process is triggered only by a master clock signal, not when any of the other input signals change. The basic building block of clocked logic is a component called the flip-flop. See more In this video tutorial we will learn how to create a clocked process in VHDL: The final code for flip-flop testbench: The final code for the flip-flop module: The waveform window in ModelSim after we pressed run, and … See more We can see from the waveform that the output signal is only updated on each rising edge of the clock signal.
