Users can use Quartus II software to add custom logic into the project and compile the project to
generate the SRAM Object File (.sof).
In addition, External Programmable PLL Configuration Controller IP will be instantiated in the
Quartus II top-level file as listed below:
ext_pll_ctrl ext_pll_ctrl_Inst(
.osc_50(OSC_50_BANK2), //50MHZ
.rstn(rstn),
// device 1 (HSMA_REFCLK)
.clk1_set_wr(clk1_set_wr),
.clk1_set_rd(),
// device 2 (HSMB_REFCLK)
.clk2_set_wr(clk2_set_wr),
.clk2_set_rd(),
// device 3 (PLL_CLKIN/SATA_REFCLK)
.clk3_set_wr(clk3_set_wr),
.clk3_set_rd(),
// setting trigger
.conf_wr(conf_wr), // 1T 50MHz
.conf_rd(), // 1T 50MHz
// status
.conf_ready(conf_ready),
// 2-wire interface
.max_sclk(MAX_I2C_SCLK),
.max_sdat(MAX_I2C_SDAT)
);
If dynamic PLL configuration is required, users need to modify the code according to users’ desired
PLL behavior.
