NOTE :As a good coding practice, there should be only one port identifier per line, as shown below Examples : Port Declaration 1inputclk ;// clock input2input[15:0] data_in ;// 16 bit data input bus3output[7:0] count ;// 8 bit counter output4inoutdata_bi ;// Bi-Directional da...
[DRC ZPS7-1] PS7 block required: The PS7 cell must be used in this Zynq design in order to enable correct default configuration. I'm new at Verilog coding, so please let m know what is the problem.
9.0 Synthesis coding styles Sunburst Design Assumption: it is generally a bad coding practice to give the synthesis tool different information about the functionality of a design than is given to the simulator. Whenever either full_case or parallel_case directives are added to the Verilog source ...

Surely we need to "assign" F a value, so coding "assign F = " would be a good start... Ok, so A xnor B... We don't have an xnor symbol! No worries, we can make A XOR B then invert the entire term! This leads to a final solution of "assign F = ~(A ^ B);" ...
SV支持对数组内变量的定位locator、排序ordering 和缩位 reduction (1) 定位 find with, find_first with, find_last with找的是数组内元素 find_index with, find_first_index with , find_last_index with找的是索引号 查看代码 查看代码 modulearray_locator;intarray[9] = '{1,2,3,4,5,6,7,8,9}...
Java提供很多线程安全的容器，为开发人员在并发编程场景下使用，通常我们会更加关注业务实现，而不关心底层...
Any code that contains the above constructs are not synthesizable, but within synthesizable constructs, bad coding could cause synthesis issues. I have seen codes where engineers code a flip-flop with both posedge of clock and negedge of clock in sensitivity list....

在verilog基础上,SV增加了二值逻辑(0、1)变量来简化运算, 包含 bit, byte, shortint, int, longint 变量。 SV中logic与verilog中的reg变量对应,为四值逻辑的无符号数;bit为二值逻辑的无符号数; byte, int, shortint, longint 均为二值逻辑有符号数,注意区分。
