Binary | To Bcd Verilog Code

Here’s a comprehensive write-up on , suitable for a technical blog, documentation, or academic submission. Binary to BCD Conversion in Verilog 1. Introduction In digital systems, binary numbers are the native representation, but many human‑interface devices (like 7‑segment displays, LCDs, or real‑time clocks) require Binary Coded Decimal (BCD) format. BCD represents each decimal digit of a number by a separate 4‑bit binary code.

// Check and correct each BCD digit // (using blocking statements inside loop) // Digit 0 (least significant BCD digit) if (temp[3:0] > 4) temp[3:0] = temp[3:0] + 3; // Digit 1 if (temp[7:4] > 4) temp[7:4] = temp[7:4] + 3; // Digit 2 (for 3-digit BCD) if (BCD_DIGITS > 2 && temp[11:8] > 4) temp[11:8] = temp[11:8] + 3; // Add more digits if needed end Binary To Bcd Verilog Code
