                3.2.1. Clock Interface
Platform Designer generates the clock source BFM for the FPGA-to-HPS alternate clock source.
| Interface Name | BFM Instance Name | 
|---|---|
| f2h_free_clk | f2h_free_clock_inst | 
Platform Designer generates the clock source BFM for each clock output interface from the HPS component. For HPS-to-FPGA user clocks, specify the BFM clock rate in the User clock frequency field in the HPS Clocks page when instantiating the HPS component in Platform Designer.
The HPS-to-FPGA debug APB interface generates a clock output to the FPGA, named h2f_debug_apb_clock. In simulation, the clock source BFM also represents this clock output’s behavior.
| Interface Name | BFM Instance Name | 
|---|---|
| h2f_user0_clock | h2f_user0_clock_inst | 
| h2f_user1_clock | h2f_user1_clock_inst |
