I have just complished the board of usb jtag emulator with a act8990,xc9536 and cypress68013.Now I have used other company's xc9536 in my board and it worked correctly.However,I can't write the vhdl code for xc9536 by myself.Who can help me?Please give me some advices?
P.S:If somebody need,i will upload my schemetic and pcb of my usb emulator.
Added after 9 minutes:
I have complished the dsp usb2.0 emulator too,but i use @ltera 7032 cpld to replace
xc9536,because i can't write the vhdl code in xc9536 too.why don't you use @ltera cpld ???
eltonjohn said: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 !
hi i need a schematic for xds510 emulator. i did xds100, tms c2000 series boards. so can u pls send me the schematic file as soon as possible.
thanks in advance
Ram
