We do this by finding a power of 10 that is greater than the RHS argument. The RHS is passed in as an integer, so we need to convert it to a binary fraction. The radix one displays in the waveforms isn’t of any consequence to the actual design operation. The following approach was used to generate a floating point number: We convert the left-hand argument to a positive binary number even if it was stored as a negative (2’s compliment). All that “dataval” is, in general, is a simple variable holding 256 possible distinct states…įurther, one normally uses radix as just a debug tool for the human debugging the design to more easily interpret things. It could be anything - context determines definition. It is observed that each digit of the decimal number is coded in binary and then concatenated to form. It could be a set of 8 independent status flags. Verilog module to convert binary to BCD (binary coded decimal). It could twos-complement value going into an ALU. Verilog module to convert binary to BCD (binary coded decimal). But whatever non-decimal representation you use, displaying it is your own function. Write verilog code in cadence to design decimal to binary decoder. d display bits as characters which represent decimal numbers. There’s no clear general purpose assertion one can apply to “dataval” in order to state that it’s value is “octal”, or “hex”, etc. Suppose, I have to represent 0.6072529350088814 in hexadecimal. Now how to interpret this “dataval” is purely a function of context. You seem to have something in mind with respect to interpreting whether a “number” is BCD, hex, octal, etc… But it’s not clear to us just what your definition is, so we can’t help you.įor most use cases one has, for example, and 8-bit wire: wire dataval
