How to do system design and verfication of video decoding ?

How to do system design?

Hi,
I want to do system design and verification of a video decoding system. How can I start from the scratch? Any informations, websites or books recommended? I decide to use SystemVerilog to do this task,how do you think?

Many thanks in advance!!

System verilog!!!!! are you planning for Synthesis or just for system design and modelling..

any simulator fully support system verilog now? IMHO, before there is such a simulator, it is hard to use systemverilog as the verification langurage.

Re: How to do system design?

I only want to do system simulation. About synthesis, I prefer to use verilog. I've heard VCS 7.0 or Modelsim 6.0 supports systemverilog, is that true?

You're right. As I know, VCS 7.0 or Modelsim 6.0 already support system verilog. You can easily use them as normal.

i think matlab is good for you

Matlab? I think it is too high level to use. How can matlab mimic necessary informations such as clock?

only for system simulation and verification u can use system c.

I think SystemC can help you a lot

If you want to do system design, SystemC is much more suitable than SystemVerilog.

SystemC is a good choice if u r familiar with C language.
Matlab is too high to do system level design. But if u only wanna verify the algorithms, Matlab is easy.

Re: How to do system design?

Iit might be good idea to use sverilog for design and systemc for verification.

SystemVerilog is not intendeed to be used for system-level modeling.
SystemC is language for you. You don't need any expensive tools in beggining (Some C++ debugger and waveform viewer are enough).
If you are talking about H.264 decoder:
- start with existing JM reference SW is OK. You need to rearange this (or rewrite in C++ to avoid C/SystemC mixing) to clearly separate functions and do profiling to help you decide about HW/SW partitioning.
- after that you need to decide about interfaces between HW modules, make SystemC wrappers around existing C++ classes (if possible, to simplified maintenance of 2 models) and imoplement those interfaces (use aproximate timing modeling). Notice that C++ model remains golden for your SystemC model all the time and both of them need to be maintained.
- make several iterrations in SystemC until you find arhitecture which satisfied your needs. Develop firmware in parallel (you don't need to choose exactly which embedded processor you will use still, except if you are going with some fancy stuff like Tensilica/Arc)
- when SystemC model is stable you could start with HDL writting. If you have nc-verilog and nc-systemc licenses you could simply replace any module in your SystemC model with Verilog and it will work (SystemC-Verilog co-simulation). Notice that you don't need to have separate block-level test environments what is great benefit. Yor SystemC model remain golden for your SystemC-Verilog co-simulation all the time.
- before go to FPGA prototyping perform gate-level (post-synthesis simulation in your SystemC environment)
- develop appropriate custom FPGA platform

I strongly agree with andromeda.

SystemC is the right choice.

SystemC will help design's quick closure a lot.

After design is stable, converting it to verilog is simple.

Systemverilog is a good choice.
You could do system design and verification using it.
And also you could do RTL coding using it.

Re: How to do system design?

system c is very good
