Reset Release Intel® FPGA IP The Reset Release Intel® FPGA IP outputs nINIT_DONE after finishing device initialization. User mode initialization can begin as soon as the nINIT_DONE signal asserts.
GTS Reset Sequencer Intel® FPGA IP Enable pma_cu_clk for the design.
GTS System PLL Clocks Intel® FPGA IP GTS System PLL Clocks Intel® FPGA IP that generates reference clock and system PLL clock.
IOPLL Intel® FPGA IP Intel FPGA Phase-Locked Loop (IOPLL Intel® FPGA IP) allows you to configure the settings of the I/O PLL.
In-System Sources & Probes Intel® FPGA IP In-system sources and probes debugging IP. The In-System Sources & Probes Intel® FPGA IP is available for all Intel device families supported by the Quartus® Prime software.
JTAG to Avalon® Master Bridge Intel® FPGA IP The JTAG to Avalon® Master Bridge Intel® FPGA IP is a collection of pre-wired components that provide an Avalon® Master using the new JTAG channel.
