VHDL是否具有三元运算符？

本文介绍了VHDL是否具有三元运算符？的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！ 问题描述 29岁程序员，3月因学历无情被辞！ 我喜欢三元运算符和if子句的简洁性。I love the neatness of the ternary operator vs if clauses.该运算符是否存在于vhdl中？我的搜索恰恰相反。我还检查了when语句，但它不是运算符，我也希望能够在流程中使用它。Does this operator exist in vhdl? My search was to the contrary. I also checked the when statement out, but it's not an operator, and I want to be able to use it in processes, too...推荐答案否在VHDL-2008上进行了讨论，但没有参与。您有几种选择。如果您的工具支持VHDL-2008，则条件支持现在可以作为顺序语句（它们以前只是并发的）而受支持，因此您可以编写以下内容：No. It was discussed for VHDL-2008, but didn't get in. You've got a couple of options. If your tools support VHDL-2008, conditional assignments are now supported as sequential statements (they were previously just concurrent), so you can write something like:process(clock)begin if rising_edge(clock) then q <= '0' when reset else d; -- ie. much like q <= reset? '0':d; end if;end process;如果您还没有2008年，只需编写一个函数（ q ）。不过，您必须针对每种感兴趣的类型编写它。If you haven't got 2008, just write a function (q <= sel(reset, '0', d)). You have to write it for every type you're interested in, though. 这篇关于VHDL是否具有三元运算符？的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持！ 上岸，阿里云！
