Hello,

I am an european citizen who wants to get in contact
with SiliconBlue Technologies and eventually get
one of their iCEman Evaluation Kits
http://www.siliconbluetech.com/iCEman_evaluation_kit.aspx

However their site indicates that there is no contact
in Europe and the indicated email never answers.

Can anybody help ?

Thank you in advance,

hello,

I am looking to create a mac controller which includes tcp/ip/dhcp.
Where can I get information on how to do this?

Within the mac controller I have started created a tx engine, rx
engine, and flow controller. My mac controller will connect to an
onboard phy chip, but I am unsure how to program the mac to interface
with the phy for IEEE 802.11 standards. Such as, when a signal is
received from phy what sequence should be executed in order to pass
that data to buffers to memory? And do tx and rx engines alternate?
After this I would like to implement dhcp/tcp.

thank you

My advice is to use Makefiles and the command line.

Good day, I have just purchased one of these myself and have the same
issue. Mine didn't come with any CD and I had to download the Adept
software.

I have emailed Digilentinc support as I think there is a driver issue.

If you check the Device Instance in device manager it shows up as
follows:

USB\VID_1443&PID_0005

In the INF file for the driver it seems to be looking for

USB\VID_1443&PID_0003
or
USB\VID_1443&PID_0001

I tried changing the INI file to PID_0005 and it did detect the driver
and install it but Export won't find any jtag scan chain devices.

The first one is a USB module and the second is a USB cable. I have
tried both and neither work.

I am awaiting a reply from Digilentinc.

Hi

I'd like to announce the availability of a Spartan 3E
FPGA development board that, while usable under Windows,
is particularly easy to use under Linux.

The reason for it's Linux friendliness is that it uses
standard USB-serial for downloads.  It does not need or
use JTAG dongles or drivers.  To the host it looks like
a FTDI USB-Serial port.

The other reason it is a nice system for Linux people
is that there is a tutorial for the board that shows
how to compile and download using a Makefile.  The
commands I use to build are something like:

	vi counter.v
	make
	make install

well, if I wanted immediate answers and perfect support,
i would go to other makers (the usual suspects).

However SBt is a new company and has been just recently
announced (unlike the "usual suspects") and they have
obviously not yet developped their distribution channels.
I am a small developper and I just want to evaluate
the technical (HS and SW) qualities of their products.
I can forgive things that a large company won't accept.
And if it fits my needs, then it is certainly possible
to overcome those representation/distribution issues.

On the SW side, I want to check how well the Linux version
performs. I'm absolutely fed up with the OS-wannabe
that was shipped with my computer and that
I could not remove because of other FPGA tools.

And if the company proposes evaluation kits,
well, the name says it all, and indeed
I would like to evaluate. It's always good
to have backup plans.

so it seems tcp/ip/dhcp would take up too many resources using an fpga
and a microcontroller would be a better approach for this.

I wasn't able to find information on how to simulate a mac controller.
Where can I find flow charts/block diagrams for this?

Hi

Very simple question: Is there another way to debug software that is
running on a PowerPC then using the RS232
interface? I am using the Platform USB cable for download but I guess
that is more for hardware debug ;)

Because the problem is, my host PC does NOT have an RS232 interface
integrated.
So it would be less troublesome if there would be another debugging
option as my machine
cause problems when trying to use a RS232 USB-to-RS232 Converter

I bought a spartan 3an board from digilent which comes with a usb

using the impact software tool; however, the software tells me that
"usb connection failed". I have also tried programming the board using
the ise software package--still a failure. I have tried re-installing
installing the drivers for the usb cable (downloading the xusbdrivers
and installing them using the command line in windows vista), but
nothing seems to work. Has anyone gone through this issue ... ?

Hi,
I am investigating the idea on building a bridge between usb and various 
electronic sensors and actuators. My idea is to connect the sensors to the 
fpga and access them from the usb port.

Each sensor needs suitables modules, like for example a PWM module if I want 
to interface a H-Bridge to drive a motor, or a I2C if I have a I2C chip.

I am able to decode commands sent thru the usb(fx2 + spartan 3E), now I need 
to know:

- what kind of virtual bus I could use, simple to use yet powerful enough. 
Ideally, I was thinking about I2C. Speed is not a concern, reliability maybe 
because I could extend the bus externally

- is it possible to configure a fpga from a pc program creating the verilog 
source file without stepping thru the ISE gui manually?

I would like to reconfigure the bus and the virtual modules on the fly, 
without dealing with the verilog code. A gui should put togheter the verilog 
code behind the scenes and program the fpga.

Interesting idea.  I'm not sure what your "virtual bus" does.
Do you mean that there is a main FPGA talking to other remotes?

SMbus, a superset of I2C, may be better for dependability.
I2C on its own can have hang-up problems unless you control
all of the devices on the bus and make sure they have time-outs.

Gabor

Gabor,
thanks for your reply. I am finding new ways to reuse software for driving 
hobby robots. The idea is that using a pc makes the life a lot easier 
(ironic?) but controlling robots with a pc alone is difficult due to the 
need for realtime control, think about motion control.

We mostly agree that part of the control (the time critical part) could be 
better done outside the pc, with a microcontroller for example.and the pc 
could simply control the execution of the realtime part with much less 
stringent timing requirements.

A fpga is a perfect "glue" to implement a  fast access (bandwidth) to 
sensors and actuators, and why not to implement inside itself the realtime 
modules and adapters for the actuators and sensors.

The mcu could be implemented as a virtual module as well, or just connected 
to this bus so it could access the sensors thru the bus itself.

I need the bus concept because I would like the ability to connect to 
different hardware, without the user's need to learn or change HDL stuff.

Let's say I have two motors, some I2C sonars and 2 encoders. I would need to 
connect them:

2 PWM module for the motors
1 I2C interface
2 Encoders interface

Application
            USB
                FPGA
                    FX2-to-robobus logic
                            <PWM module1>
                                    Actual motor1 interface
                            <PWM module2>
                                    Actual motor2 interface
                            <I2C interface>
                                    Actual sonar 1
                                    Actual sonar 2
                                    Actual sonar 3
                            <quad encoder interface 1>
                                    Actual encoder 1
                            <quad encoder interface 2>
                                    Actual encoder 2

I would like to put this stuff on a GUI, and the fpga will create on the fly 
the ability to access this 5 peripherals from the pc using dll for example.

I need it to be on the fly, not just a monolitic fpga where I could not add 
a RC servo interface without knowing Verilog.

Some modules will implement the interfacing to the actuators/sensors, like 
the  PWM and encoders interface for example. Others, like the I2C interface, 
will act as a bridge to the outside.

This approach could greatly simplify the wirings and the need for hw 
adapters to condition the signals, we just need to convert to digital and we 
are set.

On the sw side, once configured the modules based on what sensors and 
actuators I need, I could access them in a coherent way, preserving my code 
because I don't have to deal with different access methods to the sensors 
because of the different mediator (for example a different mcu), I still 
have access to a PWM no matter if my robot has different hw.

I hope I have explained better,

Giuseppe Marullo

hi......

The books that i have read,...they suggest to prefer two process model
for STATE MACHINE DESIGN i.e sequential and combinational......and iam
also follow two process model till nowdays......but the daybefore i
think i read somewhere that people prefer one process model for FSM
nowdays......
 so what is the difference having two process or one process model for
FSM other than ofcourse the presence or absence of combinational nx
state decoder......
