gEDA-user: understanding the technology rendering

[Charlls Quarra <charlls_quarra@xxxxxxxxxxxx>]

 

 Hi,

 

 I'm a newbie to the electronic design sport and im hoping to use some gEDA tools to design small circuits which i may be able to implement myself with of-the-shelf components.

 

 I've been reading about verilog and VHDL and synthesis and i've done small examples which seemingly synthesize well with Icarus.

 

 The thing i'm confused is with the target library concept. I imagine that one wants a description of a set of real solid-state components that the compiler reads and uses to compose the synthesis in a way that optimizes a number of possible constraints. But if one would want to synthesize into target technology with elements like these:

 

http://geda.seul.org/tools/symbols/library/index.html

 

 where do you find the associated target libraries for these elements? are there on the public domain? can Icarus synthesize to a custom-written technology library that includes available components, or this support must be hardcoded into Icarus for each library?

 

 Sorry for all the super trivial questions, cheers all
