| + | Gnetlist SystemC Backend | ||
| + | |||
| + | OBJECTIVE: | ||
| + | |||
| + | Transform a geda schematic into a transaction based structural systemc module. | ||
| + | |||
| + | LIMITATIONS: | ||
| + | |||
| + | 1.- Only transaction based wires are considered (wire_name<user_type>). | ||
| + | 2.- Unnamed wires are eliminated. | ||
| + | 3.- In/out ports have to be inserted manually in the sysc code. | ||
| + | 4.- Duplicated include headers are not eliminated by the backend. | ||
| + | 5.- The maximum number of object constructor parameters is 31 (attr1->attr31). | ||
