+// Module: x4xx_core
+//
+// Description:
+//
+//   This module contains the core infrastructure for RFNoC, such as the
+//   motherboard register, timekeeper, and RFNoC image core.
+//
+// Parameters:
+//
+//   NUM_DBOARDS    : Number of daughter boards
+//   REG_DWIDTH     : Width of the AXI4-Lite data bus (must be 32 or 64)
+//   REG_AWIDTH     : Width of the address bus
+//   CHDR_CLK_RATE  : rfnoc_chdr_clk rate in Hz
+//   NUM_CHANNELS   : Total number of channels
+//   CHDR_W         : CHDR width used by RFNoC
+//   MTU            : Log2 of maximum transmission unit in CHDR_W sized words
+//   RFNOC_PROTOVER : RFNoC protocol version (major[7:0], minor[7:0])
+//   RADIO_SPC      : Number of samples per radio clock cycle
