Altera MAX-II EPM240 pullup's

[Bingo600]

Hi Altera Gurus

I have a question about the pullup's on a MAXII EPM240T100C5 CPLD.

I'm a VHDL beginner just started this summer.

I'm using Quartus-II 13.0sp1 ,and have enabled pullup's om my cpld input pins in the Assignment editor.
I'm getting no errors (with respect to pullups) when building the project.

I have switched "weak pullup resistor off" in the "global fitter" (it shows on) , as i found the Assignmet editor way of selecting individual pins.


But somehow i'm not trusting the cpld to be able to switch on pullups on a selective base.

Is it just me or does it really work with individual pin pullups ?

The PU's are not visible in the RTL schematic or anywhere i can find.

Thanx for any help

Ohh: I'm doing this one for my Odroid U3

Doesn't sound actually like a technical problem...

Don't believe that you searched thoroughly. There's e.g. the report Fitter/Resource Section/Input Pins

It's not a technical problem , just a question if selective pullups works om the MAX-II
And where to verify it ?

Ohh i think i found it in the fit.rpt

Thanx for the hint FvM

I suppose i have to trust that one.
