XC4000XLA/XV - Datasheet

Hello, 

On Page 6 of XC4000XLA/XV Datasheet, there are 2 sets of numbers below the CLB RAM pictures.

Can someone tell me what they mean?

Thanks

Re: XC4000XLA/XV - Datasheet

wow
thats going back some,
I have the paper book version of that data sheet some where

Having looked a the rest of the data sheet, it looks like all diagrams have similar text in the same place, bottom right ,

So I'd guess its part of the typographic set out system used in those days, some sort of internal referance for xilinx. 



question is, what is not working that your reading this deep ?

Thanks,

We are doing QA on legacy parts for a customer and I just noticed this discrepancy, It appears that the drawings for both the single and dual are the same except for these numbers. 

I also notice these numbers are on other datasheets too.

Hi @krymson 

I believe this is just the name of the figure. If used in multiple document, the number will be the same. There seems to be one per image

Note that there are differences between the 2 waveforms, in the naming for the different times:

ex TDSS (Single Port) <> TDSDS (Dual Port)

Thanks!

Someone had mentioned to me that it could be the Mask Set but they weren't sure, But now I know.
