1.1.1 IBIS-AMI
(Ask a Question)The Tx parameters are accessed in the IBIS-AMI simulation in the following ways:
- Amplitude and de-emphasis is through the variable TX_AmpEmph.
- Driver termination is through selecting the appropriate pin in the IBIS as listed in the following table.
| Pin | Variable Name | Description |
|---|---|---|
| 5, 6 | microsemi_pf_100_tx | 100–1000 mV with 100Ω termination |
| 11, 12 | microsemi_pf_150_400tx | 100–400 mV with 150Ω termination |
| 13, 14 | microsemi_pf_150_800tx | 600–800 mV with 150Ω termination |
| 7, 8 | microsemi_pf_150_tx | 1000 mV with 150Ω termination |
| 15, 16 | microsemi_pf_180_400tx | 100–400 mV with 180Ω termination |
| 17, 18 | microsemi_pf_180_800tx | 600–800 mV with 180Ω termination |
| 9, 10 | microsemi_pf_180_tx | 1000 mV with 180Ω termination |
| 3, 4 | microsemi_pf_85_tx | 100–1000 mV with 85Ω termination |
