As far as understand, a digital IC like a DSP can be design by RTL methods and by using languages like Verilog and VHDL.

And if I'm not wrong, we cannot yet program pure analog chips by using a language so SPICE simulators are used for design(?)

But for a mixed signal design of a chip, does that mean one expert desing the digital part(by using HDL) and the other expert analog part(by using SPICE)? So it takes two expert desing engineers for a mixed signal design? And they integrate it together in a way?

  • \$\begingroup\$ Thanks, I was mostly wondering is the analog IC design part done only by SPICE software? \$\endgroup\$ – user1245 May 20 at 13:32
  • \$\begingroup\$ SPICE is only a simulation tool, not a design/layout tool. Other tools are required for that, and I'm not sure what the state of the art in that area currently is. \$\endgroup\$ – Dave Tweed May 20 at 13:37

design is done in the human brain.

simulators are for verification
