NOTICE: August 08, 2016 Si2 EMAIL REFLECTOR MAIL IS BEING REJECTED BY SOME COMPANIES
NOTE: Si2 External IP Address Changes
* Recently, Si2 switched network service providers and subsequently, all of its external IP addresses.
* Email reflectors are used by our many Production and Open Standards collaborative research/development working groups.
* If your company uses access control lists to manage email traffic, and you send emails via the Si2 reflector list system, then the following information will be relevant to you.
CONTACT YOUR IT DEPARTMENT TO VERIFY YOUR CURRENT OR FUTURE STATUS:
After the Si2 IP changes, reflector list messages that previously appeared as email coming from 220.127.116.11 will now show as email coming from 18.104.22.168. Any access control lists that reference the old Si2 IP (22.214.171.124), will need to be updated to the new Si2 IP (126.96.36.199) in order to restore previous functionality. Additionally, make sure that your company IT has Si2 white listed!
The OpenPDK Coalition
was founded in mid-2010 with the goal of defining a set
of open standards to allow an OpenPDK to be created once
and then translated into specific EDA vendor tools and
specific foundry formats. This will allow an OpenPDK to
be as portable across foundries and as agnostic to EDA
tools as possible. The Si2 OpenPDK standard will enable
greater efficiency in PDK development, verification, and
delivery. It will provide equivalent support to all
stakeholders: foundries, EDA tool vendors, IP providers,
Open Process Specification (OPS) version1.1 will be
delivered in late 2013. This will extend the Open
Process Specification with connectivity below metal 1 to
allow full Layout vs. Schematic (LVS)capability and
allow EDA vendors to start building tools compatible
with the specification.
A Pcell Working Group was formed in early 2013 to work
on the concept of a pcell language that supports a
“write once and use many” approach. This is increasingly
important as more design kits are being produced by
fewer experienced developers for multiple EDA platfoms.
The key requirement of a common coding language is to
define a grammar based on an existing language that can
be translated into the major pcell and callback
languages already in use in the industry without
requiring API’s not owned and supported by the OpenPDK
initiative. The requirement supports innovation by
allowing embeddable proprietary code and alternative
A translator to convert the Open Process Specification
(OPS) to the OpenAccess Technology Database will be
delivered in 2013. This will be a basic translator that
will be an example of how to move the XML data described
in OPS to the binary OpenAccess incremental technology
database. It is planned to be extensible so that EDA
vendors and user companies may take the example and
extend it for their own needs.
ESD Protection Design Methodology Specification V1.0 was
published in 2013, The design of ESD (Electro-Static
Discharge) protection devices in an integrated circuit
should be evaluated and verified at all stages of a
standard circuit design flow starting from the Cell
Schematic level and ending at the full chip layout
level. A comprehensive set of ESD checks should be
verified using appropriate tools at each of these levels
to ensure that the integrated circuit has robust ESD
protection. This Methodology document should be of value
to the EDA and semiconductor industries and Si2 has made
this document available to the entire community.
A standard Tool Interface Specification was published in
2013. An example of a commonly adopted format among EDA
vendors is an ASCII netlist representing a hierarchical
description of wires and their connections. However,
this description can vary according to the target
that reads a netlist. Each target application expects
the circuit description in a certain format that suits
its needs. It is the responsibility of the netlister
tool to generate the output description of the design in
a structure and a format that is acceptable to the
target application. Tool interfaces describe how process
design kit components are presented to a target
netlister. This standard tool interface specification
all companies to present information in a standard
manner to a variety of applications.
