Re: pc based oscilloscpe - help needed
Have you developed your own software to get output on the PC or are you using a FPGA based solution? I know of a lot of implementations in which a signal is fed into a FPGA and it displays the output on a PC. The main issue with those is to get the...
Hi,
I do not know which version you are using since you did not mention it but here are a few links which might be useful to you:

Hi,
What kind of projects? You want to write some kind of VHDL code to design a DSP, or you want to do a project based around a DSP Processor?

Re: Help me out
Hi,
I think if you are planning on doing a custom layout than you would definetly be using Cadence Vitruso.
For Synthesis - Synopsys Design Compiler (Design Vision)
For Place & Route - SoC Encounter or Silicon Ensemble
Hope this helps.
If you need any further answers do...

Re: adc converter
The outputs of the comparator should be a thermometer code with a single transition. However, sometimes a lone 1 will occur within the strings of 0s (or a 0 within the strings of 1s) due to comparator metastability, noise, cross talk, limited bandwidth, etc. These bubbles...
Hi,
Incase you have the book "Digital Integrated Circuits" by Jan Rabaey & Chandrakasan & Borivoje you can refer on Page 137.
Otherwise this might be a little useful as well:

adc converter
Hi,
It depends on what architecture you want to use. But a simple way for designing an ADC you need a Comparator, than you need Bubble Error Correction Circuitry and afterwards you need a ROM Encoder to convert the thermometer code to Binary Code. And than you are more or less...
Hi,
I assume you mean a RTL-> GDSII flow. In that case you need Modelsim to write your code in VHDL, for synthesis you can use Synopsys tools which will map the libraries according to the process that you are going to use for the chip tapeout. After Synthesis the tool will generate a .v file...
Well I found some answers to my last questions which are posted below. If some one could further verify their utility it would be nice.
