In this post, I would like to talk about VHDL’s crown jewel: how it preserves determinism in a concurrent language. Here is a figure of how it works:What you see is a simplified example of VHDL’s delta cycle algorithm in action. Delta cycles are an HDL concept used to order events that occur in zero physical time. The red circles refer to signal value updates. The blue squares are process evaluations.A delta cycle starts with a number of signal value updates. A signal value update may trigger…

在这篇文章中，我想谈谈VHDL的皇冠上的宝石：它如何以并发语言保留决定论。以下是它的工作原理图：您看到的是VHDL增量循环算法的一个简化示例。Delta周期是一个HDL概念，用于排序在零物理时间内发生的事件。红色圆圈表示信号值更新。蓝色方块是过程评估。增量循环从多个信号v开始 alue更新。信号值更新可能会触发…
