PC Oscilloscope Design using Altera

I am wondering if it is possible to design a PC oscilloscope using VHDL and Altera.

The port used of the PC will be the serial port.

Thanks.

Depends if you want real-time or just a logic analyzer/capture style. Serial is pretty slow, but otherwise, I don't see why you can't do it. You still need interfacing circuitry around the FPGA

yeah why not.

ive got a better idea. dont interface it with a PC. interface it with a VGA monitor. you can buy kits that have connectors for VGA/LCD monitors and comes with the code for the drivers.

you will have to make a GUI for the scope in VHDL with all the control knobs on the screen and the display. it will be a cool real-time embedded system.

EDIT: if that sounds like rocket science to you (it does to me ) then have a look at this https://www.fpga4fun.com/digitalscope.html

Hi


The easy way in a Altera device is to place a signal tap analyser inside a device
montoring a couple of input pins , and taking this pins to the circuit you need to have alook at , the analyzer software is already built into the quartus software.

well there is a application note on www.xess.xom which describes Oscilloscope using Verilog.

View it u will get benefit

Whay you do not use Xilinx Chipscope, or Altera SignalTap?

Please read more carefully topic ...

It is for PC interfaced oscilloscope, based on FPGA, but not for debugging FPGA internals ...

Sorry I made a mistake, however we can use them as a Logic Analyzer not just a debug tool!

Thanks for the link given.. its a big help.. but im a bit confuse.. what FPGA did the author of this links used??? im currently using spartan 3E.. do you have any link similar to the link u posted that uses spartan 3E???

Why do you think it can't use Spartan 3E?

im just new to use vhdl.. im searching for a reference for my project and i found the link,. when i started to simulate the code given im confused on how to map the components.. can u help me?
