For an integer defined with range 0 to 1000, and if the integer is an incrementing counter. What happens if the signal that resets an integer counter...
Hello , I am starter in VHDL . Is there any difference between two sources below? They are different i think. first source uses vector signal in the entity body. second source uses vector signal in the architecture body. is ther any difference? for example concurrent process or seque...
ss: MACHINE WITH STATES (s0=1, s1=0); -- reset state is s0, state register is non-zero BEGIN ss.reset = reset; -- assert this signal to properly reset the state machine <...> For VHDL, the initial state may be defined by anIFstatement and a reset signal. ENT...
This is where the "application-specific" part of ASIC comes into play. The transistors are arranged so that they perform a specific function or set of functions, such as digital signal processing, data encryption, or even the specific computations required for cryptocurrency minin...
most of the work of the CPLD is done on the computer. Open the integrated development software (Altera Max+pluxII) → draw a schematic diagram, write hardware description language (VHDL, Verilog) → compile → give the input excitation signal of the logic circuit, simulate, and check whether...
signal x,w,y: bit_vector (1 to N); -- in signal l,r,z: bit_vector (1 to N); -- out The port map for p1 is similarly afflicted. p1: lab32 port map (x,w,y,l,r,z:bit_vector (1 to N)); It should either have named or positional elements without a ...
signal data_out1, data_out2: unsigned (31 downto 0); begin uut: rom port map ( addr1 => addr1, addr2 => addr2, data_out1 => data_out1, data_out2 => data_out2 ); Additionally, it is a 32-bit ALU with 6-bit opcode, and it is a two-port data memory w...
Here’s a simple example of an AND gate in both languages. An AND gate has two inputs and one output. If the inputs are both equal to 1, the output is 1. If they are not equal or if both are set to 0, the output is 0. VHDL describes an AND gate as: entity my_and is...
Added user ability to increment a signal with a binary redix in either Verilog or VHDL format. Improved system messaging or user warnings and prompts. Modified the operation associated to the deletion of a component block. The deletion now intuitively deletes all diagrams and other contents of th...
What is a "$width" violation, and how do I correct it? Solution In back-annotated (timing) simulation, the timing information is taken into account when simulation is run using the SDF (standard delay format) file. The "$width" message occurs when the pulse width of a specific signal ...
