1.5.1. Command Line Flags for regress.sh
| Flag | Description | Legal Values | Default | Required |
|---|---|---|---|---|
| -a | Path to AFU source1 | <valid pathname> | - | Yes |
| -r | Creates a directory to build the simulation. | <valid pathname> | - | Yes |
| -s | Simulator type | vcs, modelsim, or questa | VCS if installed; otherwise, Modelsim or QuestaSim | No |
| -p | Target platform name | Directory containing an OPAE installation | Board specified by OPAE_PLATFORM_ROOT | No |
| -v | AFU configuration variant |
Depends on AFU selected (-a flag). | Depends on AFU selected (-a flag). | No |
| -i | Path to OPAE installation | <valid pathname> | - | No |
| -m | Local memory model | EMIF_MODEL_BASIC, EMIF_MODEL_ADVANCED | EMIF_MODEL_BASIC | No |
| -b | Path to OPAE source | <valid pathname> | - | No (except for NLB) |
Target Platform Name -p
The target platform name is used by the Platform Interface Manager (PIM).
-p defaults to discrete if OPAE_PLATFORM_ROOT is undefined or does not specify a valid OPAE release. discrete models a generic PCIe card with two banks of local memory
注: Intel recommends setting OPAE_PLATFORM_ROOT as described in Setting Up the Environment.
AFU Configuration Variant -v
regress.sh looks in the hw/rtl/filelist*.txt file to determine the configuration variant. When you specify the variant as -v <variant> , regress.sh looks in hw/rtl/filelist_<variant>.txt for the AFU RTL source files.
The default value of -v depends on AFU selected (-a flag):
- Native loopback (NLB) AFU: RTL files listed in hw/rtl/filelist_mode_3.txt
- Other AFUs: RTL files listed in hw/rtl/filelist.txt
Path to OPAE Installation -i
You must specify the install path if you do not use the RPM flow. If you are using the RPM flow, the install path is not required. 2
Local Memory Model -m
-m selects the simulation model for FPGA private memory.
- EMIF_MODEL_BASIC uses a simple System Verilog array to model dual banks of DRAM.
注: Intel recommends using EMIF_MODEL_BASIC for a faster simulation.
- EMIF_MODEL_ADVANCED uses an advanced cycle-accurate model of the EMIF memory controller.
Path to OPAE Source -b
注: This flag is required when simulating the NLB AFU in the regression flow. -b is used to locate the application source relative to the OPAE source for NLB.
