Hi,
I'm designing mixed signal circuits.
digital circuits are synthesized by Design Compiler and P&R is performed by using Astro.
In the floorplan stage, i made core area, power/ground ring, horizontal power/ground rail for standard cells.
But, after making floorplan, input/output singal pin position is determined randomly.
I want the place the 32 output pins at the left side, and 4 input pins at the right side, none at top and bottom side.
In addition, i want to determine the space between each pin by myself, not automatically.
How can i do this?
I does not use Digital I/O PAD, because digital circuits are merged with analog circuits.
So, i think that i cannot do this using TDF file. Is it right?
