How to quickly find device category?

How many categories do you have? How many cells in the library? I'm very surprised it's that slow. There's the obvious choice of using something like forall or exists to abort the search once you've found it, but that would only (on average) halve the search time.

Andrew.

I would like to clarify.
I've a simple form where I try to show my devices, it's category and etc.
And if I try fill category column my form generate about 2-3 seconds, without categories - form generate - immediately.

I tried it on my library with 21 categories and 599 cells - and by running the profiler on your code above, running 100 times (in a for loop) it took 5.92 seconds (so that's 0.06 seconds to run once). However, in the profiler, it's spending nearly all of the time in ddCatFindCat.

I suggest you use ddCatOpen() instead of ddCatFindCat - this is MUCH faster - the run time reduced to 0.28s for 100 runs. ddCatFindCat has some code in there to traverse the category hierarchy to find a sub-category, whereas in this case you're only accessing the top categories, I think.

I still don't know why yours is so slow though - perhaps you have some hierarchical categories too? Anyway, probably ddCatOpen is the man for the job - otherwise you should contact customer support so that an application engineer can have a look with you.

Call hiFlushCIW() between doing the printf() and before you call ipcWait() to force the CIW output to be flushed and to appear immediately.

Your second question is a bit vague - end of text file? When? Do you mean if you use infile() to read it and then gets() to read lines from the file? If so, the end of the file is reached when gets() returns nil. If you mean something else, you'll need to be more precise.

By the way, asking a collection of random unrelated questions in the same thread is against the forum guidelines (the pinned post at the top of each forum) because it makes it much harder for anyone else who is searching for a similar issue to know that a post is relevant to them.

Andrew.

Hi Andrew!

I'm understand and sorry. Simple this question is so small to create a separate topic.

About file. I have text file with saved DRC error markers.
I try to use gets() == nil, but I don't know why, it's doesn't work for me.

Rule 568 : Cnt_b: Min. Cont sep. = 0.18

in this file for first error I can collect all coordinates till find next error, but in the end I try to check
while(gets(string inFile)
some code

coord = pcreCompile("^(-*\\d+\\s*)*$");
pcreExecute(coord string);
cmdRes = pcreSubstitute(coord "\\0");
if(cmdRes && cmdRes != "" then
;;remove \n symbol
rexMatchp("\\([^\n]*\\)\n\\([^\n]*\\)" cmdRes);
cmdRes = rexSubstitute("\\1 \\2");
l_coord = append1(l_coord cmdRes);

if(gets(nextLine inFile) == nil
this I want call my procedure to cope markers, but loop simple finished.

P.S. If need I can create a new topic.

Given that you've only shown part of your code, it's hard to see what you're doing. Given that you have a gets() in the while loop - and maybe a second gets reading nextLine later on, it's unclear to me what's going on or what's not working. It's also odd that you're using both pcre and rex functions - looks a little unstructured.

Andrew.
