This plugin provides an API to read STIL formatted ATE pattern files, allowing STIL pattern snippets to be embedded within Origen pattern logic:
# Add pins (and groups) from the given STIL pattern to the DUT
OrigenSTIL.add_pins("#{Origen.root}/vendor/mode_entry.stil")
# Execute the vectors within the given STIL pattern, sending them to the current tester
OrigenSTIL.execute("#{Origen.root}/vendor/mode_entry.stil")This API is used by the Origen pattern conversion command when the input format is STIL:
origen convert my_pattern.stil -e v93k
Any valid STIL should be parsed, however not all of it will be understood or handled yet.
Additionally, there are some restrictions around formatting within the Pattern (vectors) blocks which are mainly to allow Origen to execute them quickly without having for formally language-parse this section.
Here are some of the main known limitations currently:
- MatchLoop statements are not supported
- V/Vector blocks must begin and terminate within a single line
- Block comments (
/* ... */) are not supported within Pattern blocks, though inline comment style is (// ...) - Macros are not supported
- Shift and other scan test constructs are not supported
- Only cyclized vector statements are supported
- Hexadecimal and decimal pin value assignments within vector blocks are not supported
- Subtraction within pin group definitions is not supported
The plugin is more useable than the above list might suggest, since many tools which render STIL will themselves emit a constrained subset of the full language. However, support for these additional features is being added on an as-needed basis.
Please open an Issue ticket if you find the need for a missing feature, ideally including a STIL snippet showing an example.
