Hi,
I've heard about ESL tools like Mentor Catapult C and Cadence C-to-silicon.
As far as I read, they are very powerful and mature.
Also, Mentor Graphics website, they pretend that it has unmatched efficiency. Even Ericson developers couldn't make any closer to its results - tis is mentioned in the user testimony on mentor's website-. The same for Alcatel and many companies.
My question is: if so, why digital design companies still use veriolg or vhdl for their design? Why not using ESL tools directly? It's easier, shortening development time.
I know that these tools convert first to verilog or vhdl first.
My question in a modified way: why to start from the RTL level, not ESL ?
