For example, after CycloneIV device power up, what is the initial value of the internal registers? I found a interesting thing: usually,we set the initial value for the registers like this: always@(posedge clk or negedge reset) reg <= 0; But when you trace the reset...
// Verilog Example of Shift Register for Delay: reg[3:0] r_Shift; always@ (posedgei_clock) begin r_Shift[3:1] <= r_Shift[2:0];// Shift Left r_Shift[0] <= i_Data_To_Delay; // Bit 3 of r_Shift has been delayed by 4 clock cycles ...
Create a Mux in Verilog and VHDLA multiplexer (or Mux) is another word for a selector. It acts much like a railroad switch. This picture shows two possible source tracks that can be connected to a single destination track. The railroad switch controls via some external control which train ...

Verilog-XL does not mark macro modules(which it expands inline) as cell instances. Refer to the PLI 1.0 Reference and User Guideand theVPI Reference and User Guidefor more information about access routines thatrecognize cells and the use of cells in delay calculation. Note:You do not need ...

若有以下程序 #include void sp(int *a) { int b = 2; *a = *a * 2; printf("%d, ", *a); a = &b; *a = *a * 2; printf("%d, ", *a); } int main() { int k = 3; sp(&k); printf("%d", k); return 0; } 则程序的输出结果是（...
This coding style does address Verilog X optimism incasestatements, but not in wildcard case statements likecasexandcasez. Both of these coding styles can be processed by synthesis tools without problems. However, some linting tools may flag X assignment, and it is sometimes a controversial practic...

When the Duchess asked Ogilvie to put off the cigar after the deal had been made, how was Ogilvie's reaction?
