is there the same silicon chip used in different housings

Hi, if one can buy the same size in different housings, will the chip be the same for the housing with lowest and highest Pin Count? Would e.g. same silicon chip being housed in 484Pin BGA (i.e. h...

Hi Ethan,

the PinOut Files include power, GND, MSEL, JTAG, ... but no cross-ref for the user I/O Pins. Nevertheless, if the sof and pof include the device ID (more than family and size but also package?) they cannot be identical for sure.

As the programmer in JTAG mode and Auto-Detect does not include package information, I would assume these are not coded in HW (if the silicon is same, it cannot be harware coded imho). Thus, the BGA should accept the pof generated for the RQFP, shouldn't it?

Thanks and KR

Hi,

As far as I know, the Jtag could get a jtag id while auto detecting, and the jtag id is unique for each package.

What is the specific OPN for the two devices(QFP and BGA)?

You could check the jtag id in the "pgm_parts.txt" located in Quartus install path.

./quartus/bin64

Via Jtag, you could check the header of the configuration file pof, sof or jic.

I think you could try to configure with rbf or rpd file if the header is the gate.

Thanks,

Ethan

    Hi,

    this is the extract from the pgm_parts.txt file from Quartus 9.0 for the device:

    EPF10K100A 88 20 18 15 0 EPF10K100A 0 0 10 0 1 0x001000DD 0xFFFFFFFF 0 155/000 0
    EPF10K100AB356 88 20 18 1 356 EPF10K100A 0 0 10 0 1 0x001000DD 0xFFFFFFFF 0 155/000 0
    EPF10K100AB600 88 20 18 1 600 EPF10K100A 0 0 10 0 1 0x001000DD 0xFFFFFFFF 0 155/000 0
    EPF10K100AF484 88 20 18 4 484 EPF10K100A 0 0 10 0 1 0x001000DD 0xFFFFFFFF 0 155/000 0
    EPF10K100AR240 88 20 18 12 240 EPF10K100A 0 0 10 0 1 0x001000DD 0xFFFFFFFF 0 155/000 0

    I assume the 0x001000DD is the device ID, i.e. identical for all housings...

    The POF on the other hand includes in the header complete device ID (with housing and speed grade).

    The two devices are in detail the (currently used) EPF10K100ARI240-3 and the (intended) EPF10K100AFI484-3.
