Mentor SystemVerilog training offers intense, practical instruction for verification engineers including best practice usage of SystemVerilog
Verilog 的数据类型主要是线网和变量,即 wire, reg, integer,都是四值逻辑(0、1、x、z) 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, short...
(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};intres[$];initialbeginres= array.find(x)with(x>3);$displ...
参考自https://stackoverflow.com/questions/22070608/why-using-zero-timing-0in-verilog-is-not-good-practicea. designer通常使用#0来避免两个过程块之间存在竞争,#0 会使进程暂停,并在其他的block结束后,在Inactive region开始执行,这样带有#0的block就是最后执行的,但如果有多个block都加了#0,那么谁是最后执...
2.0 Verilog & SystemVerilog case statement modifiers Before going into detail about all of the case statement modifiers, we should look at the big picture as it relates to full_case, parallel_case, priority and unique. First ask yourself the questions: Why are the full_case parallel_case ...

Digital hardware is often simulated using a discrete-event approach. TheVeriloglanguage, for example, was designed as an input language for a discrete-event simulator. The VHDL language also has an underlying discrete-event model of computation. ...
(called universal digital blocks, UDBs) ■ Cypress provided peripheral component library, user-defined state machines, and Verilog input Low Power 1.71 to 5.5 V operation ■ 20 nA Stop Mode with GPIO pin wakeup ■ Hibernate and Deep Sleep modes allow wakeup-time versus power trade-offs ...
It would also be possible to resume a parent process when the first of a number of child processes terminates by using an event or list as follows. The effect is similar to thefork-join_anyconstruct in SystemVerilog: sc_process_handle h1 = sc_spawn(&proc1, "proc1"); ...
(EDA) software tools to assist in the design process. Chip design using EDA software tools generally involves an iterative process whereby the chip design is gradually perfected. A top-down design methodology is commonly employed using hardware description languages (HDLs), such as Verilog or VHDL...
