Request Design Configuration
| Notify the relevant design authority, or authorities, of the need to identify the source and target libraries. |
Request Library Configuration
| Notify the relevant design authority, or authorities, of the need to identify the source and target libraries. |
Understand Change Request
| The Design Authority needs to understand the request and the technical change needed to either the design, libraries,
cells or cell hierarchy. It may be necessary to modify the description of the CR to meet the intended mission. This may
require collaboration with others and reference to supporting information such as the original requirement, specification,
defect or test. |
Modify Change Request (optional)
| Depending on the outcome of the CR analysis it may be necessary to update the CR which may cause it to be returned to the
CCB, depending if the update is minor or major. |
Analyze Design Configurations
| Analyze design configurations if they are provided, analyze these to validate that they are relevant to the CR. Mark them
as valid or invalid. Update the CR to reflect the findings. Understand the libraries and cells required for the change or
created by the change. |
Analyze Library Configurations (optional)
| If library configurations are provided, analyze these to validate that they are relevant to the CR. Mark them as valid or
invalid. Update the CR to reflect the findings. |
Identify or Select Libraries
| It be possible that the select the libraries to work with (as sources) and to target (for the results) from the description
alone, for instance through naming conventions. It may be necessary to look within the libraries to see that indeed the
intended items are at the given location. It may be necessary to inspect planned or pending releases to identify the
target. |
Select Cell to Modify
| The identity of the cell or cell hierarchy to modify needs to be defined sufficiently. Again this may be by description and
identifiers alone or it may be necessary to inspect the library and cells. Furthermore some view of other CRs in play is
necessary to understanding other planned or pending changes. It can also be prudent to inspect high priority defects which
haven’t yet been launched into CRs to see what may be impacted if an emergency CR is launched. |
Analyze Cells in the Library Configuration (optional)
| Exploring the cells in terms of their state, function and quality will help confirm the validity of the library and cell
configuration. Understanding other work in progress can also help establish the stability of the configuration. |
Analyze Cell Hierarchy (optional)
| Exploring the cells in terms of their composition and inclusion helps further confirm the validity of the library and cell
configuration. Similarly understanding other work in progress can also help establish the stability of the configuration.
This step may well require collaboration with other design authorities. |
Assign Design Configuration
| Design Library configuration descriptors including links are added to the CR and approved by the design authority, along
with any notes about the risk associated with these choices, such as due to other CRs in play and their links. It may be
necessary to withhold this step until the CR is replanned. |
Assign Library and Cell Configuration
| Library and cell configuration descriptors including links are added to the CR and approved by the design authority, along
with any notes about the risk associated with these choices, such as due to other CRs in play and their links. It may be
necessary to withhold this step until the CR is replanned. |
