In this example, the $signed function is used to convert the 8-bit data to a signed value, and the $unsigned function is used to convert it to an unsigned value. $display("Unsigned data: %0h", unsignedData) $display("Signed data: %0h", signedData) Here's an example to demonstrate the usage of signedness conversion functions: module SignedUnsignedExample For such situations, you can use $signed and $unsigned functions: In some scenarios, you may need to convert the signedness of expressions without changing the actual data type. The DataReceiver module then uses $bitstoreal to convert the 64-bit vector representation back to a real value. 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
