| | 3 | When using a VCI-AVALON component, you must define explicitely the three Avalon parameters: |
| | 4 | {{{ |
| | 5 | address_width |
| | 6 | data_width |
| | 7 | burstcount_width |
| | 8 | }}} |

| | 10 | So you may factor out common parameters putting them at the end of the list of the VCI parameters as shown in the following platform_desc example: |
