--- title: VLSI 3 tags: VLSI --- # VLSI 3 - Behavior and Structural Model ## Models 1. Dataflow model(適合簡單組合邏輯) - Concurrent Signal Assignments 2. Behavior model(適合稍微複雜一點的) - sequential Assignments(signal + variable) - Inside Process Statements 3. Structural model(適合電路太大的話,可以拆成好幾個部分) - Netlist ## Statements ### Process Statement #### If statement - Includes Latch(記憶裝置) ##### Review :::spoiler 點開看 Latch ![](https://i.imgur.com/FBiWVsY.png) ::: :::spoiler 點開看 DFF ![](https://i.imgur.com/HidVnV6.png) ::: ### Variable Assignment Statements $\vdots$ 好多的 Statements 自己去看講義啦ㄏ ## Notes for homework Clock Cycle: 20ns = 50MHz - 可能會有 reset - 提到 reset 的 statement - wait - if <!-- end of note -->
