[SI-LIST] Re: Layout service recommendations

Hello Martin,

For the layout try ACDI, they are pros, prompt and know how to handle
complex designs as well as simple ones.
www.acdi.com

Other than that, be papered:
* try to come with a recommended placement.
* know which are the critical nets and/or components.
* you should prep a "constrains file" which is mostly a word document with a
block diagram, and a list of all critical nets and the constrains (for
instance dram[15..0] no longer than 2inch, and plus minus 250 mils within
the group)

Good luck

Gil G
