Digital Circuit will be represented and simulated via ModelSim simulator. Consider the digital circuit represented below. Two eight-bit wide data input ports are added. The result is then used to set one of eight output lines according to predefined thresholds. Code this design in VHDL and verify its correctness by writing a testbench. Simulate the design using the ModelSim simulator. What is the difference between the data type bit and the data type std_logic in VHDL? What is the difference between the data type bit_vector and the data type std_logic_vector in VHDL? What is the difference between VHDL signals and variables? Which data types are natively present in VHDL?

Hello there, i am krishna [FPGA design engineer at LogicTronix]. I have good expertise with VHDL programming, FPGA Design and Embedded Design. Your questions answer [in short] The bit data type is used for such variable which can have only two states '1' or '0'. While the std_logic is used for the variable which can have more than two states value, std logic datatype can hold 9 different state values as '1'- high, '0'-low, 'X','Z'-high impedance, 'U'-undefined etc. And vector on the bit and std_logic is used to define the array type of variable. Signals are like as the jumpers or wires and variables are just the normal variable on other languages.

Bit has only 2 values '0','1' std_logic has 9 values 'U','0','1','X','Z','-','H','L','W' Bit and bit_vector are natively present in VHDL. I assume that the inputs numbers are unsigned. Is it right ?
