[SOLVED] general questn about synthesis

[cyrax747]

Hi

Normally rtl written in verilog or vhdl is synthesized and carried forward till chip fabrication in ASIC.But some times code is also written in embedded c or c++ langauges,How does this code get synthesized and moved forward till chip fabrication?

But some times code is also written in embedded c or c++ langauges

C/C++ for hardware modelling? Where did you get this info?
I have never heard about it!
I think you are confusing b/w hardware modelling using hardware descriptive languages and writing code for embedded systems using C/C++.

A piece of sw. code written in C/C++ may reside within the memory of an embedded system. The hardware, which was already designed using HDLs (Verilog or VHDL), executes the code from the memory. This piece of code is sometimes called the firmware. The hardware + firmware together constitutes an embedded system.

You can synthesize a limited subset of C/C++:

I understood what "dpaul" has said,my doubt was cleared and again doubt raised ,by jbeniston's reply.I think use of c and c++ ,we can synthesize code and go ahead to chip fabrication.

Yes, you can use the above tools to synthesize C to Verilog, then use standard ASIC flow from there.
