Re: PLX PCI9050 problem
penrico :
Is the computer failed using AMI BIOS ?
If I am correct, check the BAR requirement. It need to be all '1' from MSB to your size.
For example, if you request 32 bytes I/O space.
Your BAR should exactly 0xffffff20.
Some configuration like...
synplify chipscope
Hi,
I met some issue while using Chipscope with synplify 7.2.1.
here is my steps:
1) Using generator to generates icon & ila
2) Insert it to my verilog code (/* syn_black_box... */ is existed)
3) Synthesis ==> Succesful
4) Start ISE, Add source (My...
Hi,
Does any one has experience about the logic translation ?
I want to convert multiple logic standard to TTL (RS-232, ECL, TTL, SSTL2...) @ 500 MHz.
Discrete or curcuits would be fine ..
thanks
I think EZ-USB is still good for production maintain.
Its 8051 firmware is downloaded from device driver.
So with new driver, your hardware provides more functions.
For plug into a 5V pci slot, you need to add extra 5V -> 3.3V logics.
You can refer to xilinx solution about their 1.5V virtex to 5V PCI.
There is no 5V input tolerance in Virtex 2.
pci 3.3v to 5v
Hi,
If you want to use IDT quickswitch as 5V <-> 3.3V translation,
please forget the AN_11 from IDT. It is wrong!!
According the circuits test, the output voltage is not what they said.
By the way, xilinx provides a way to use the IDT quickswitch.
In this application note...

Hi,
I use the serial montior from hxxp://www.hhdsoftware.com/
It can sniff the windows serial port. Not only the really port
but also the emulation port (Like bluetooth or IR serial port).
I used it as port monitor to check protocol between device driver
and my firmware...
Be care about the moisture.
It will destroy you bga while heating.
After done this, I got 100 % sucessful in both smt production or
the bga mounting machine.

I would like to design with AMBA.
For high bandwidth, it provides the AHB/ASB with pipeline feature.
For low speed periperal, it defines the APB.
WISHBONE is also good, it is easy and left TAG for user-defined using.
But there it is not suitable for pipeline operation.

apb specification
Hi,
In hxxp://www.gaisler.com/ Jiri built a GNU sparc v8 compatible processor named LEON. Inside there is a AHB <-> APB bridge..
Although it is written in VHDL. Maybe it gives you some hints.
