In this example, the DataSender module uses $realtobits to convert the temperature real value into a 64-bit vector representation. Module DataReceiver(input logic realData) Īssign temperature = $bitstoreal(realData) Here's how you could use $realtobits and $bitstoreal functions to convert real values for data transmission: module DataSender(output logic realData) Īssign realData = $realtobits(temperature) Suppose we have two modules, DataSender and DataReceiver, which communicate real values with each other. Let's look at a simple example to better understand real number conversion functions. Practical Usage of Real Number Conversion Functions $bitstoshortreal: Converts a 32-bit vector representation back to a shortreal value.įor more information on real number data types, refer to the post Real, Shortreal, and Realtime Data Types in Verilog and SystemVerilog.$shortrealtobits: Converts a shortreal value to a 32-bit vector representation.$bitstoreal: Converts a 64-bit vector representation back to a real value.$realtobits: Converts a real value to a 64-bit vector representation.$itor: Converts an integer value to a real value.

$rtoi: Converts a real value to an integer by truncating it.

The following real number conversion functions are commonly used: These functions allow you to convert values to and from real number values and make signed or unsigned values conversions. In Verilog and SystemVerilog, several system functions can handle real number values (the real and shortreal types).

In this tutorial, we'll go over several important conversion functions that will make your life as a designer much easier. They help in handling and converting different data types seamlessly and efficiently. Conversion functions play a crucial role in digital design with Verilog and SystemVerilog.
