點為之識?識睇唔難,就算未學過嘅IT人都應該睇得明大部份。識寫同識好嘅design practice又唔同level。

Haven’t used this ages, the company (Canadian of course) I used to work for would code rtl in vhdl, synthesized netlist in verilog. Ever since cadence started to support both in the same design, and acquired IP from US companies, everyone just shifted to verilog.  

Vhdl uses variables and signals, much easier to do code review.

Hold on and let me digest what you said... did you mean they write behavioral rtl in vhdl and then synthesize it into structural/gate level verilog?

yes, synthesis tool reads in vhdl and spits out verilog netlist, i.e. frontend was all vhdl, backend all verilog.

Interesting, was it because of vendor requirement?

no, at the time the anal-retentive old seafood disliked the looseness (pun) of verilog and preferred the more deterministic, intentional syntax/typing of vhdl.  Simplest example is one can't assign vectors of different width together. I guess they hated cleaning after shxt from new grads like me.

verilog netlist is a given, I don't recall seeing a vhdl netlist ever.

There are lots of type A personalities in management. They may be good for the company (when they are right), but it’s not fun working for them. Plus nothing gets done when you’ve got a bunch of them in a meeting room. </end rambling>

[taguid=5692270]in_my_memory[/taguid] 其實你講既野 我公司前幾年做過類似既野 通常一轉會改善本身公司已有既code base 同埋公司睇既係我用幾多時間做到幾多既野
如果End user 睇唔到 公司高層興趣會不大
講番我之前既project 我做發電廠protection system. 我地想將現有用左30年既system 一次過改哂 for 將來二十年用
用左四年時間 50個engineer 最後因爲成本太高產品本身唔會賺到錢比人terminate 左成個project
炒左幾個大粒既
其實就咁睇你咁講好難知到應唔應該
同埋新code 有機會有新bugs 公司未必想改

nowadays nobody cares about coding style/re-usability, management just want to know the metrics (milestones/performance/coverage) i.e. 快靚正

No, depend on which industry that you are working on. we are still very serious about coding style and reusability.

However, cost is everything. You dont care if IOS is written by other langauge if the interface is exactly the same. however, you care about how much apple charge you for an iphone.

You will learn if your company rebuild the system, but this may not good for the company

I kind of agree and disagree. My current company hires a lot of very smart and very technical people (to put it nicely), but they are also the most anal butthead idealogues I’ve ever worked with. These techies would argue endlessly over things you thought nobody would care about. It’s sort of like a mirror of Discuss :lol

those "architects" can argue all day long, I dialin to all meetings anyway, so little loss of productivity from my end.

我有睇關於香港嘅新聞,very sad

近排較忙,少咗上香討唞唞氣嘅時間。

樓主都應該好忙,失咗蹤...
