What's IPgen?

IPgen is a lightweight IP-core package synthesizer from abstract RTL sources. You can implement both AXI4 and Avalon IP-core by using the provided abstract interfaces.

• ipgen_master_memory: memory-mapped access interface (master)
• ipgen_slave_memory: memory-mapped access interface (slave)
• ipgen_master_lite_memory: memory-mapped access lite interface (master)
• ipgen_slave_lite_memory: memory-mapped access lite interface (slave)

Installation

Requirements

• Python3: 3.6 or later

• Icarus Verilog: 10.1 or later

sudo apt install iverilog

• Jinja2: 2.10 or later
• Pyverilog: 1.1.3 or later

pip3 install jinja2 pyverilog

Install

Install IPgen.

python3 setup.py install

Getting Started

You can use the ipgen command from your console.

ipgen

You can find the sample projects in 'tests'. Now let's see 'tests/memcpy'. There is an input source code.

• memcpy.v : User-defined Verilog code using IPgen abstract memory interfaces

Then type 'make' and 'make run' to simulate sample system.

make build
make sim

Or type commands as below directly.

ipgen default.config -t memcpy -I include tests/memcpy/memcpy.v
iverilog -I memcpy_ip_v1_00_a/hdl/verilog/ memcpy_ip_v1_00_a/test/test_memcpy_ip.v 
./a.out

IPgen compiler generates a directory for IP-core (memcpy_ip_v1_00_a, in this example).

'memcpy_ip_v1_00_a.v' includes

• IP-core RTL design (hdl/verilog/memcpy_ip.v)
• Test bench (test/test_memcpy_ip.v)
• XPS setting files (memcpy_ip_v2_1_0.{mpd,pao,tcl})
• IP-XACT file (component.xml)

A bit-stream can be synthesized by using Xilinx Platform Studio, Xilinx Vivado, and Altera Qsys. In case of XPS, please copy the generated IP-core into 'pcores' directory of XPS project.

IPgen Command Options

Command

ipgen [config] [-t topmodule] [--ipname=ipname] [--memimg=memimg_name] [--usertest=usertest_name] [-I include]+ [-D define]+ [file]+

Description

• config

  • System configuration file which includes memory and device specifications

• -t

  • Top-module name of user logic, default: 'top'

• --ipname

  • IP-core package name, default: '(topmodule)ip(version)'

• --memimg

  • Memory image file in HEX (option). The file is copied into test directory. If no file is assigned, the array is initialized with incremental values.

• --usertest

  • User-defined test code file (option). The code is copied into testbench script.

• -I

  • Include path

• -D

  • Macro definition

• file

  • User-logic Verilog file (.v)
