5.2. RAM: 2-Port IP Core Signals (True Dual-Port RAM) for Intel® MAX® 10 Devices

Table 18.  RAM: 2-Port IP Core Input Signals (True Dual-Port RAM)
Signal Required Description
data_a Optional Data input to port A of the memory. The data_a port is required if the operation_mode parameter is set to any of the following values:
  • SINGLE_PORT
  • DUAL_PORT
  • BIDIR_DUAL_PORT
address_a Yes Address input to port A of the memory. The address_a port is required for all operation modes.
wren_a Optional Write enable input for address_a port. The wren_a port is required if you set the operation_mode parameter to any of the following values:
  • SINGLE_PORT
  • DUAL_PORT
  • BIDIR_DUAL_PORT
data_b Optional Data input to port B of the memory. The data_b port is required if the operation_mode parameter is set to BIDIR_DUAL_PORT.
address_b Optional Address input to port B of the memory. The address_b port is required if the operation_mode parameter is set to the following values:
  • DUAL_PORT
  • BIDIR_DUAL_PORT
wren_b Yes Write enable input for address_b port. The wren_b port is required if you set the operation_mode parameter to BIDIR_DUAL_PORT.
clock Yes The following list describes which of your memory clock must be connected to the clock port, and port synchronization in different clock modes:
  • Single clock—Connect your single source clock to clock port. All registered ports are synchronized by the same source clock.
  • Read/Write—Connect your write clock to clock port. All registered ports related to write operation, such as data_a port, address_a port, wren_a port, and byteena_a port are synchronized by the write clock.
  • Input/Output—Connect your input clock to clock port. All registered input ports are synchronized by the input clock.
  • Independent clock—Connect your port A clock to clock port. All registered input and output ports of port A are synchronized by the port A clock.
inclock Yes The following list describes which of your memory clock must be connected to the inclock port, and port synchronization in different clock modes:
  • Single clock—Connect your single source clock to inclock port and outclock port. All registered ports are synchronized by the same source clock.
  • Read/Write—Connect your write clock to inclock port. All registered ports related to write operation, such as data port, wraddress port, wren port, and byteena port are synchronized by the write clock.
  • Input/Output—Connect your input clock to inclock port. All registered input ports are synchronized by the input clock.
outclock Yes The following list describes which of your memory clock must be connected to the outclock port, and port synchronization in different clock modes:
  • Single clock—Connect your single source clock to inclock port and outclock port. All registered ports are synchronized by the same source clock.
  • Read/Write—Connect your read clock to outclock port. All registered ports related to read operation, such as rdaddress port, rdren port, and q port are synchronized by the read clock.
  • Input/Output—Connect your output clock to outclock port. The registered q port is synchronized by the output clock.
rden_a Optional Read enable input for address_a port. The rden_a port is supported depending on your selected memory mode and memory block.
rden_b Optional Read enable input for address_b port. The rden_b port is supported depending on your selected memory mode and memory block.
byteena_a   Byte enable input to mask the data_a port so that only specific bytes, nibbles, or bits of the data are written. The byteena_a port is not supported in the following conditions:
  • If the implement_in_les parameter is set to ON.
  • If the operation_mode parameter is set to ROM.
addressstall_a Optional Address clock enable input to hold the previous address of address_a port for as long as the addressstall_a port is high.
addressstall_b Optional Address clock enable input to hold the previous address of address_b port for as long as the addressstall_b port is high.
Table 19.  RAM: 2-Port IP Core Output Signals (True Dual-Port RAM)
Signal Required Description
q_a Yes Data output from Port A of the memory. The q_a port is required if the operation_mode parameter is set to any of the following values:
  • SINGLE_PORT
  • BIDIR_DUAL_PORT
  • ROM
The width of q_a port must be equal to the width of data_a port.
q_b Yes Data output from Port B of the memory. The q_b port is required if you set the operation_mode to the following values:
  • DUAL_PORT
  • BIDIR_DUAL_PORT
The width of q_b port must be equal to the width of data_b port.
