Implement the novel router architecture.

make both a 2D and a 3D version? Maybe run both on 8x8x2 noc

64 nodes = 32 nodes times 2 = 8x4x2 NoC

1. Create folder that contains all scripts for the simulations (scripts/feature_paper).
2. Create and include figures for examplary reports.
3. Create and include figures for performance of router model.
4. Include the csv file therefore.
5. Include the latter figure also in the documentation of this simulator!

• basically urand script. already well-documented.
• link them with entry points
• write nice user manual
• also include vhdl synthesis

Define a novel power model, based on transmission matrices, for leackages within routers. Probabaly we will need matrices for buffers, cb and something clever for the routing unit.

Need to define models first! Implementation is easy going.

Include the functionality from the old version into the new code. Also improve the usage of the python scripts by good documentation.

• simulation of urand with infinite buffers.
• using HXYZ and XZY
• check buffer usage
• same simulations for 8 and 4 flit deep buffers.
• then adopt the buffer depth to acutally used number and then to 50% of that number. individually per layer and channel!
• report the performance figures!

use the topology files as already defined once (you will remember, those from hetero_XYZ_same clock etc.)

Write routine and assert the correct values

Routers are not actually double data rate, but on the negative clock cycle the valid signal is set false in order to make the receive function sensitivity okay. That's bad... probably

These scripts will generate reports.

• performance from routers
• power from vhdl
• generate power profile in routers
• generate link matrices
• run matlab to evaluate these
• area from vhdl
• generate tex for report and compile

• transmission matrices
• Link.cpp write and test
• nice data format to pass info to matlab
• test matlab

If I use

[Config]
simulationTime = 100000
flitsPerPacket = 32
bitWidth = 8
benchmark = synthetic
libDir = config

[Synthetic]
simDir = sim
restarts = 16

[Report]
bufferReportRouters = [5, 6, 9, 10, 21, 22, 25, 26, 37, 38, 41, 42]

routing = XYZ
clockDelay = [1, 1, 1]

vcCount = 4
topologyFile = network
flitSize = 64
portNum = 7

config.ini file in the bin folder and run python configure.py, the resulting network.xml file is not correctly connected. It has diagonal links that you can see using python plot_network.py

The correct file must follow 3D mesh, i.e. that each router is only connected to direct neighbors in west, east, north, south, up, and down direction. Please fix this in the xml_writers.py

Current config scripts generate synthetic only. The application scripts are mostly done from previous scripts, but they need integration.

Important todos:

• use configparser
• remove duplicate code

Probably some overflow.

Whenever a simulation is started, an empty log.txt is created. This old feature must be removed.

• topologyFile must move to network .
• libdir must be in CONFIG
• raname NOC_3D_PACKAGE to NOC
• simulation_time, num_cores must be renamed to camelcase and unclear why simtime double
• rout_algo is double, pls remove
• move NETWORK to hardware!
• Merge ROUTER and NOC in hardware
• remove router_pl, since it is redundant
• rename URAND to SYNTHETIC.

Add support for:

• calculation of number of flits based on packet size and the link widths
• Variable length of packets

Within the GlobalReport.h member variables for all energy events are given. Implement those in the router model!

• simple config.ini for network size?
• script to generate simulator configuration
• script to generate VHDL code

Timing of send and receive is broken. Example:
9080ns: Router4[ East0] - Send Flit [B_74613: 4-->22]
9080ns: Router5[ East0] - Send Flit [H_74610: 4-->22]
9080ns: Router4[Local0] - Receive Flit [B_74616: 4-->22]
9080ns: Router5[ West0] - Receive Flit [B_74613: 4-->22]
9081ns: Router4[ East0] - Send Flit [B_74614: 4-->22]
9081ns: Router5[ East0] - Send Flit [B_74611: 4-->22]
9081ns: Router4[Local0] - Receive Flit [B_74617: 4-->22]
9081ns: Router5[ West0] - Receive Flit [B_74614: 4-->22]
9081ns: Router6[ West0] - Receive Flit [B_74611: 4-->22]

B_74613 is send and received in same time, B_74610 is missing completely, although later its sent

• move parameters to config.ini in folder /bin/power/

• Handle Credit increment in receive functions.
• get rid of flowcontrol intermediate DS in router

in factory

changed datadestination to task instead of node. where is the mapping applied?

[Report]
bufferReportRouters = []

in configure.py generates xmls that break simulator

in config.xml it's =5 and in the code it's =2.

still waiting for files from Bremen

Add support for:

• Reporting of Latecies, injeciton rates etc.
• Same metrics such as Booksim

Implement test scripts for:

• 4x4 and 8x8 urand.
• netrace

use python scripts, called from travis.yml

Delete ac and as

Xis etc are router coordinates. No need for them in config.ini, they must be a level deeper and automatically generated for the whole network. Thanks.
