hello, I try to understand something. Let's consider a VHDL/Verilog design. If i want that design on a chip, what should i do? I mean what is the next step in order to get an actual chip which implements that design?

Do you mean how to order an ASIC with your HDL design?

First you need to do the synthesis by putting in some constraints if that apply to your design like area and timing constraints.

After synthesis your gate level netlist is ready which can be used for the physical design flow which is basically a technology and foundary dependent flow, the steps include floorplanning with the placement of macros and and then placement where you place the actual standard cells of your design,
After which you perform two levels of routing the global routing and the detailed routing.
After which your layout is ready.
Each of the stage has its own constraints.

After the generation of the layout which is generally a gdsii format you basically perform physical verification where you do the lvs and the drc checks.

Static timing analysis is basically a timing analysis tool measuring your timing related issues like slack worst negative slack total negative slack etc. And is performed at almost every step of physical design.

All the physical design steps are managed by the CAD tools, the most common eda providers are synopsys cadence and mentor graphics they have a range of tools catered to your specific needs.

Thanks  
If we take it from the synthesis report , is it enough?
