| I want to directly query odb database. How can I do that? There is no command for that.
|
| I found some ord::xxx commands by searching the net but there is no proper documentation with all commands. |
|
|
| ### titan73 |
| also found odb::xxx. No documentation either.
|
| Most functions required a self argument.
|
| Tested "::odb::dbBlock_getPowerDomains [::odb::dbBlock]" to get power domains but it crashes. |
| |
| ### titan73 |
| I got to something using orf and odb to get the created power domains:
|
|
|
| foreach pd [::odb::dbBlock_getPowerDomains [::ord::get_db_block]] {
|
| puts "[::odb::dbPowerDomain_getName $pd]"
|
| }
|
|
|
| I think I get the idea. A pity it's not documented.

| We use swig on https://github.com/The-OpenROAD-Project/OpenROAD/blob/master/src/odb/include/odb/db.h so the APIs and comments there should be a guide. If you have specific questions please ask. |
|
|
| ### titan73 |
| Ok thanks. It helps. Although not all methods have comments. dbPowerDomain for instance.
|
| How does int& is supposed to be mapped in tcl? Ex: bool getArea(int& x1, int& y1, int& x2, int& y2); |
