SumpPump Specifications/Requirements?

[swissMac]

Hi everyone

I read some great work going on here.
Question, is there a single page that defines the specification/requirement of the SumpPump?

I read its going to be faster that the saleae but how will it compare to a 'proper' USB analyser? i.e pre trigger/post trigger, adjustable thresholds levels for different logic type CMOS TTL etc???

some of theses specs turn the saleae from a challenger into a toy, I'm just wondering where we're all aiming at. My initial assumption is a challenger for a serious analyser, but I see no specs to work to?

I'm not trying to 'diss' the great work going on here but if we're not looking at a serious bit of kit then is it not another saleae?

SM.

(edit. ) are these the final specs?

swissMac,

That message is a good summary of what we are trying to accomplish with the first revision of this hardware.

For specifications of what the VHDL core is capable look at http://www.sump.org/projects/analyzer/.

The client software is really pretty good and has good triggering support.

As far as supporting different logic types the FPGA itself has good support for several different logic types. I've never tried to change logic types on the fly and do not know off the top of my head if it is possible but it is possible to change the logic type to whatever you want in the ucf file and re-synthesize the design.

This is an overview of what the Spartan 3E supports:
Spartan-3E FPGAs support the following single-ended
standards:
• 3.3V low-voltage TTL (LVTTL)
• Low-voltage CMOS (LVCMOS) at 3.3V, 2.5V, 1.8V,
1.5V, or 1.2V
• 3V PCI at 33 MHz
• HSTL I and III at 1.8V, commonly used in memory
applications
• SSTL I at 1.8V and 2.5V, commonly used for memory
applications

Hi Jack
many thanks for filling in the blanks,
I'll check out VHDL core

Other stuff that would be of interest is the state mode.
Basically if it was cheaper I'd be a happy owner of a zeroplus or logicport analyser

Had a look at the link enclosed , specs are nice. Don't see anything about upper and lower threshold settings, noisy environments need this?

the add on board  2.5 - 5.0V Input Stage Using TI SN74ALVTH16244
 could be enhanced to cope with all forms of voltage from -ve to +ve levels? and most likey be part of the solution rather than an add-on?

Finally the protocols mentioned that can be analysed are IC2 and SPI, any others?   CAN, Manchester, SPDIF, etc?

what should be nicer here is the PC client running in java and thus hopefully portable to any OS?

I hope I'm not going round and round in circles as its taken me a looooong time to decide on an analyser and this sounds even better if those fine tweaks can also be put in place
