A 2-to-1 multiplexer consists of two inputs, one select input and one output. Depends on the select signal, the output is connected to either of the inputs. Since there are two input signals only two ways are possible to connect the inputs to the outputs, so one select is needed to do these operations. VHDL […]

This decoder takes as its input four bits that represent a binary coded (BCD) value and generates a 7-bit output to drive a seven-segment LED. Each segment is a small LED, which glows when driven by an electrical signal. The segments are labelled from a to g as shown in the figure below: VHDL

1. It is a radiating element which has the shape of a horn. It is a waveguide, one end of which is flared out. 2. A waveguide, when excited at one end and open at the second end, radiates. 3. However, radiation is poor and non-directive pattern results because of the mismatch between the waveguide

1. An SRAM block is a two-dimensional (2D) array of SRAM cells, where each cell can store one bit of information. If we need to store m items with n bits each, we can use an array of m × n SRAM cells. 2. The dimensions of the SRAM array are called its aspect ratio.

Verification using Simulation: 1. Verification is the process used to demonstrate the correctness of a design. We verify that our design description meets its functional and timing specifications before the target PLD is programmed. 2. Verification using simulation can show the existence of errors in a design, but cannot prove that a design is correct.
