UVM原始碼學習 uvm queue
uvm queue從uvm object擴充套件而來，是對sv queue的擴充套件。sv中，佇列queue有以下幾種方法 假設已定義int q q.push back a 元素a壓入隊尾 q.push front a 元素a壓入隊首 q.pop front 彈出隊首元素 q.pop back 彈出...
UVM原始碼學習 uvm misc
uvm misc，uvm雜貨鋪，定義了uvm用到但不好歸類的雜散的task function class。uvm void，基類，所有uvm類都直接或間接擴充套件自uvm void。uvm void中沒有任何成員變數或方法，是個抽象類，其作用與c語言中的void相似。uvm scope stack，...
UVM原始碼學習 uvm barrier
uvm barrier直接擴充套件自uvm object，提供多程序間的同步機制。簡單講就是使用者設定乙個閾值，每個等待同步的程序在執行完之後進入wait for等待事假觸發，當進入wait for的程序數達到閾值時觸發該事件，所有等待同步的程序跳出wait for繼續執行，從而實現多個程序的同步。...
