Hi, recently I've been working with Cadence SKILL and I have several questions.

First, From my understanding if i do something like
wi = "1u"
I am making a string. If I have a variable, let us say width1, which contains an integer/float number inside, how do I make the variable number a string.

Second, how do I truncate a variable (float number)?

Third, it is a continuation from this answer

Mr. Hughes said "Where w and l are the parameters' name and can be found from CDF Edit Form."
where can I exactly find this parameters' name?

Thank you for helping me, I really appreciate it.
 

sprintf(
{s_Var | nil }
t_formatString
[ g_arg1 ... ]
)

Formats the output and assigns the resultant string to the variable given as the first argument. This is a syntax form

Ex:sprintf(numString "%d" 10) : converts 10 to "10" and stores it in numString.

Hope this helps .I did not quite get your second query..

w and l are the parameters' names!

In the icfb CIW (window) use Tools -> CDF -> Edit... . A new window called Edit Component CDF will open. Fill in the Library & Cell Name (e.g. via Browse), then you can see and/or change these default parameters (change: only if you have write access right, of course).

To see/change the w, l, (m, f, ...) parameters of individual devices, just select the component and [q]uery its Object Properties in the appropriate Edit Object Properties window.

thank you all. My second question was, let's say you have a number 1.666666e-10 but you want to make it 1.66e-10, how would you do that?

Try:
sprintf(s_Var "%4.2e" 1.666666e-10)
It will be rounded up, of course, but I guess that's what you would like anyway ;-)

Thank you very much.

Added after 1 hours 22 minutes:

Sorry to ask another question. The code
sprintf(s_Var "%4.2e" 1.666666e-10)
provided by erikl works perfectly. However, I was wondering what would I do to produce the same thing with a float number output instead of a string.

Also, how would I convert from string to float number.

Thanks.
 

Hint: Look at SKILL commands atoi() & atof()
Use these with sprintf() & you can convert no.s to strings & vice-versa with relative ease.

;)

Best regards,
I-FAB

TY cop02ia.

I have another question regarding LVS. I used SKILL to create an instance so my layout can include that instance. (easier to flip and shift) For some reason, during LVS, it doesn't recognize the instance. Only after I flatten the instance that the LVS passes. Is there anyway to pass LVS without flattening my instances?

Thank you guys. Help is appreciated.
