Designing a Binary Coded Decimal (BCD) Converter Using Verilog

In this article, we will explore the design of a Binary Coded Decimal (BCD) converter using Verilog. The BCD converter is an essential component in digital systems that converts binary numbers to decimal numbers. In this design, we will utilize various datapath components such as adders, subtractors, incrementers, decrementers, multipliers, comparators, shifters, registers, multiplexers, decoders, encoders, and logic gates.

The BCD converter is a structural connection of these datapath components, which are modeled behaviorally as separate Verilog modules. The design of the BCD converter involves selecting the necessary datapath components to implement the conversion process.

In this article, we will focus on designing a Binary to BCD converter using Verilog. We will also explore how to extend this design by adding a refresher circuit and a multiplexer to create a Multiplexed BCD Display Driver that can display the Tens and Ones outputs of the Binary to BCD Converter on 7-segment LED displays.

The Multiplexed BCD Display Driver is designed to control when each 7-segment display will be illuminated, allowing both displays to appear as if they are simultaneously displaying a digit. This is achieved by repeatedly displaying a digit on each display faster than the human eye can respond.

In this design, we will utilize the multiplexer component to select between the Tens and Ones output of the Binary to BCD Converter. We will also use the SegSel output from the 7-segment LED decoder designed in Lab 2 to control which 7-segment LED display would be used to display the 4-bit binary number.

The design of the Multiplexed 2-digit BCD Display Controller is an extension of the Binary to BCD converter. It involves adding a refresher circuit and a multiplexer to create a controller that can display the Tens and Ones outputs of the Binary to BCD Converter on the corresponding 7-segment LED displays.

In conclusion, designing a Binary Coded Decimal (BCD) converter using Verilog is a complex task that requires careful selection and connection of datapath components. The design of the Multiplexed BCD Display Driver adds an additional layer of complexity, as it requires the use of a refresher circuit and a multiplexer to control the illumination of each 7-segment display.

However, with a thorough understanding of Verilog and the various datapath components available, designing a Binary Coded Decimal (BCD) converter using Verilog is achievable. The design presented in this article provides a comprehensive overview of how to implement a Binary Coded Decimal (BCD) converter using Verilog and extend it to create a Multiplexed BCD Display Driver that can display the Tens and Ones outputs on 7-segment LED displays.
