What is the difference between Verilog and VHDL?

• Verilog is used for FPGA design, while VHDL is used for ASIC design

• Verilog is a procedural language, while VHDL is concurrent

• Verilog is case-sensitive, while VHDL is not

• Verilog is a hardware description language, while VHDL is a programming language

What is the purpose of the 'initial' block in Verilog?

• To trigger events on clock edges

• To interact with an HDL simulator using a programming language

• To convert a high-level description into a netlist

• To ensure the design was manufactured correctly

What is the role of the 'assign' keyword in Verilog?

• To define the beginning and end of a block of code

• To make continuous assignments between variables

• To specify a case statement for conditional branching
