10.1.6. Intel Stratix 10 EMIF IP RLDRAM 3 Parameters: Diagnostics

Table 334.  Group: Diagnostics / Simulation Options
Display Name Description
Calibration mode Specifies whether to skip memory interface calibration during simulation, or to simulate the full calibration process.

Simulating the full calibration process can take hours (or even days), depending on the width and depth of the memory interface. You can achieve much faster simulation times by skipping the calibration process, but that is only expected to work when the memory model is ideal and the interconnect delays are zero.

If you enable this parameter, the interface still performs some memory initialization before starting normal operations. Abstract PHY is supported with skip calibration.

Abstract phy for fast simulation Specifies that the system use Abstract PHY for simulation. Abstract PHY replaces the PHY with a model for fast simulation and can reduce simulation time by 3-10 times. Abstract PHY is available for certain protocols and device families, and only when you select Skip Calibration. (Identifier: DIAG_RLD3_ABSTRACT_PHY)
Show verbose simulation debug messages This option allows adjusting the verbosity of the simulation output messages. (Identifier: DIAG_RLD3_SIM_VERBOSE)
Table 335.  Group: Diagnostics / Calibration Debug Options
Display Name Description
Quartus Prime EMIF Debug Toolkit/On-Chip Debug Port Specifies the connectivity of an Avalon slave interface for use by the Quartus Prime EMIF Debug Toolkit or user core logic.

If you set this parameter to "Disabled", no debug features are enabled. If you set this parameter to "Export", an Avalon slave interface named "cal_debug" is exported from the IP. To use this interface with the EMIF Debug Toolkit, you must instantiate and connect an EMIF debug interface IP core to it, or connect it to the cal_debug_out interface of another EMIF core. If you select "Add EMIF Debug Interface", an EMIF debug interface component containing a JTAG Avalon Master is connected to the debug port, allowing the core to be accessed by the EMIF Debug Toolkit.

Only one EMIF debug interface should be instantiated per I/O column. You can chain additional EMIF or PHYLite cores to the first by enabling the "Enable Daisy-Chaining for Quartus Prime EMIF Debug Toolkit/On-Chip Debug Port" option for all cores in the chain, and selecting "Export" for the "Quartus Prime EMIF Debug Toolkit/On-Chip Debug Port" option on all cores after the first.

Enable Daisy-Chaining for Quartus Prime EMIF Debug Toolkit/On-Chip Debug Port Specifies that the IP export an Avalon-MM master interface (cal_debug_out) which can connect to the cal_debug interface of other EMIF cores residing in the same I/O column. This parameter applies only if the EMIF Debug Toolkit or On-Chip Debug Port is enabled. Refer to the Debugging Multiple EMIFs wiki page for more information about debugging multiple EMIFs. (Identifier: DIAG_RLD3_EXPORT_SEQ_AVALON_MASTER)
First EMIF Instance in the Avalon Chain If selected, this EMIF instance will be the head of the Avalon interface chain connected to the master. For simulation purposes it is needed to identify the first EMIF instance in the avalon Chain. (Identifier: DIAG_RLD3_EXPORT_SEQ_AVALON_HEAD_OF_CHAIN)
Interface ID Identifies interfaces within the I/O column, for use by the EMIF Debug Toolkit and the On-Chip Debug Port. Interface IDs should be unique among EMIF cores within the same I/O column. If the Quartus Prime EMIF Debug Toolkit/On-Chip Debug Port parameter is set to Disabled, the interface ID is unused. (Identifier: DIAG_RLD3_INTERFACE_ID)
Use Soft NIOS Processor for On-Chip Debug Enables a soft Nios processor as a peripheral component to access the On-Chip Debug Port. Only one interface in a column can activate this option. (Identifier: DIAG_SOFT_NIOS_MODE)
Table 336.  Group: Diagnostics / Example Design
Display Name Description
Number of core clocks sharing slaves to instantiate in the example design Specifies the number of core clock sharing slaves to instantiate in the example design. This parameter applies only if you set the "Core clocks sharing" parameter in the "General" tab to "Master" or "Slave". (Identifier: DIAG_RLD3_EX_DESIGN_NUM_OF_SLAVES)
Enable In-System-Sources-and-Probes Enables In-System-Sources-and-Probes in the example design for common debug signals, such as calibration status or example traffic generator per-bit status. This parameter must be enabled if you want to do driver margining using the EMIF Debug Toolkit. (Identifier: DIAG_RLD3_EX_DESIGN_ISSP_EN)
Table 339.  Group: Diagnostics / Miscellaneous
Display Name Description
Export PLL lock signal Specifies whether to export the pll_locked signal at the IP top-level to indicate status of PLL. (Identifier: DIAG_EXPORT_PLL_LOCKED)
