24 Dec 2004 2:08 xds510 schematic

I needed an emulator XDS510 and they are so pricy .So i'm in the process of designing one
But i will go with USB so i can power the chips too..

Here is the first schematic .I will update it later !
I intent to use the parallel port drivers of the original XDS510 ..But i will raise an exception every time CCS tries to access the parallel port hardware and gain control and re route the commands or data through the FTDI drivers.

By the way i just passed the 1000 post mark!!

This is basically the idea ..by using the 256 lower addresses of the FT232C in MCU host mode to drive the high byte of the TAP 74ACT8990 in one single WRITE(16 bit ) MCU ACCES
But for reading is a little more problematic .SO i was compelled to get the 16 bits in two MCU 8 bit read accesses .Once again by using the higher addresses to enable the latching of the second byte to be read in a the next MCU 8 bit access cycle .!!

I wanted to design something cheap .As a solution to those expensive tools
here i used just cheap TTL logic .. and the Ti Tap to avoid dealing with a very complex software interfacing .On top of that Ti doesn't discloses their EMULATORs SDK .. But with an agreement .So to develop those tools you have to be a company on that line of work ..So i need to stick and use their DRIVERS !

The real fun will begin now with the soft !

Hi eltonjonh,

I think, you miss XDS510 control register in your hardware. It is separate from
ACT8990. Take a look on ES10 files at: h**p://www.agelectronics.co.uk/download.html for register description.

Best regards,
Stoyanov

Hi eltonjonh,

Sorry,
It was better to read carefully before posting.
My note above is related to XDS510 ( ISA Interface), you plan to
made something based on XDS510PP ( parallel port).
I was learning some of old ISA EVM's - 5x, 54x, made by TI. It seems,
they differ from XDS510 exactely in the control register - different adresses,
bits are located in a different way too.
Anyway, I hope my link will help Smile

Good luck!

HI STOYANOV .. Well i didn't ..i know i haven't finished the final version
I have been envolved with so many soft issues! ..i will updated it later with all the same funcionnalities

But BEFORE i go full speed i will do another PROJECT with the OLD 34C60 i want to see if is posssible to replace it with a fast MCU .. then all is ok!

Hi,
I find some XDS510.. made in China.
Maybe they aren't as good as the original.
But they are more cheap.

It's not that easy IMHO. If you look at the XDS510PP schematics, the act8990 outputs don't go directly to the pod. They are combined with some auxiliary, unknown signals (PP_CS2, HPI_CS and TBC_CS) by using a GAL. I think it's necessary to know how these signals are generated.

Your idea is good, but I think it would be much easier to intercept the I/O read/writes for the original XDS510 card (the ISA one), where the auxiliary register is well documented.

By the way, does someone know where I can find the XDS510 ISA board schematics? Wink

I know that you have the equations (everybody has them Wink

). What you don't have is how the signals that go into the GAL are generated.

If you just trap the I/Os and send them to the TBC, those signals (which probably are generated by writing the output configuration register of the ppc34c60) would be missing.

I alson know how they are generated .! .
What i would like to know is IF THERE IS A MARKET for such a PRODUCT!
There is also the possibility of implementing all the emulator with a fast MCU
but the 74ACT8990 has to be emulated as well ! ..but anyways great and useful projects ..

Really? Can you tell it also to me, then? Smile

I was planning to build something like your device; the software doesn't scare me very much, I'm more concerned about these hardware details. I think they are the real PITA.

I doubt that a product like this would be legal to sell; XDS510 is a proprietary technology, you need to sign a NDA and buy the SEPK from TI if you want to build and sell your emulator (I know that because I've asked them Smile

I think that using a FPGA (just like SD does) would be more appropriate.

Yes, I've downloaded that also, but I think it would be more practical to buy the real thing (some US brokers still sell it).

I've found almost all of the informations to "emulate" XDS510 (the ISA version); in this case the control register is almost straightforward, there is just one signal for which I haven't found references yet, i.e. the bit 14 (EVTSYNC, event sync select). Do you have any ideas on what is its function? Maybe it is just an enable signal for the EVENT pins of the SN74ACT8990?

However, I hope that "goodman" will give us some further informations about the chinese vendor. Before taking the solder iron, I would like to test the "el cheapo" XDS510PP interfaces... Smile

Hello eltonjohn!
So for you USB emulator the problem is with the drivers and you have two choises :
1. write own one which is a very tuff task envolved with a lot of hacking
2. use TI`s drivers but trough debugger which catch the exeptions and then redirect the data to your device
I have such a debugger which I used when I was making XDS510PP_CPLD but trough this debugger the thigs are slowing down ..
Btw I was sart making USB emulator but I don`t have time to finish it ..

They use the CPLD to replace GAL & 74HC244,and the USB chip to finish the SMC34C60's job.
Now i'm trying to make a USB XDS510 by myself,but I don't know the euqation in the GAL .I have try to use some sofeware to conver the JED file into ABEL file,but it seems not work.Can some one tell me the inner logic relation in the GAL ?

THANKS A LOT!
I have used some software like jed2abl to conver it and got the same answer.But i am not sure about whether it wrong or right. Maybe after i finished my current work,i have first to check the emulator's pcb to get a real scheme.

Hardware making to develop not difficultly, it is more difficult to write driver under CCS. I talked about it to Sergey Markov(designer of SM510PCI card), he has told, that for this purpose package Sourceless EPK (Texas Instruments) is necessary.

Hi, eltonjohn.
I just download your schematic.
but how can I control FT2232?
I think that it is a just UART Emulator

i think if you use ft245 to replace the smc34c60 maybe simple,if you used other usb chip the driver is difficult.

It is better to address all the question to developer.
His nick is SM

You can ask him at

or at

You can use english

If you will have problems with russian language, ask me.

Hi all,

Where are people up to with this project? Im about to need to program/debug my target PCB & all I have is an EzDSP board. Im doing all this at home & theres no way I can afford US$2000 for an emulator, CCS, etc.

Do we know of a USB emulator we can get from China, etc?

Eltonjohn, hows your project going?

Cheers,
Pete
