Can autorouters take advantage of moving around I/O pins on a microcontroll= er=20 to best fit the component layout or does it strictly follow the schematics? When I do designs with microcontrollers (which seems to be everytime now) a= nd=20 especially with the PIC24/32 that has peripheral pin select, I don't finish= the=20 schematics until I have placed the components on the board and routed most= =20 fixed connections so that I can decide which I/O-port pin or peripheral=20 function will be used for what. But I guess I can just do the same with the autorouter - connect the fixed= =20 connections, aoutoroute, see which moveable connections will be best and=20 connect these in the schematics, autoroute again and so on? /Ruben > On 16/05/2013 07:07, IVP wrote: > >> autorouter (I use eagle) can connect them, then why not > >> use the result?
