Hi @taichi-ishitani ,

I'm trying to understand your NOC TB here, it would be great help if you can have a presentation on this. I have already gone through your work " rggen " which was awesome and impressive, trying to understand this NOC TB the same way. If you have a presentation explaining how this works and it's structure..It will be great.

Thanks !

Do you know why? Thank you for your reply!

tnoc_packet を送受信するための interface を定義する。
また、パケットからフリット、フリットからパケットに変換するモジュールも作成する。

tnoc_fifo_sr を削除して、tnoc_fifo_mem にまとめて、tnoc_fifo に改称する。

router 内の input/output block の flit 接続には、各ルート用のポートが使用されている。
記述簡略化のため、ポートを配列に変更する。

AXI ブリッジを #51 に対応させる。
AXI のリードデータチャンネルには、転送サイズを示すフィールドはない。
なので、ブリッジ内で、

• 要求パケットから、転送サイズを取り出して保持
• byte_count/byte_offset を管理

する必要がある。

これを保持するバッファが必要になるが、パラメータで保持する値を指定する。
バッファのインデックスは、

• location_id/tag の幅が ID 幅より小さい場合
  • location_id/tag そのもの
• location_id/tag の幅が ID 幅より大きい場合
  • location_id/tag から CRC を計算し、その上位ビット

とする。インデックスがリクエストの ID となる。

データ幅が 32 bit の場合のシミュレーションを実施する。

転送サイズを示すフィールドを変更する。
バス幅変換をしやすくするため。

• 要求
  • burst_length を byte_length に変更
    • 単位はバス幅ではなく、バイトに変更
• 応答
  • byte_size を追加(ヘッダー)
    • 要求で来た値をそのまま返す
  • byte_offset を追加(ヘッダー)
    • バス上でどの位置から始まるかを示す
    • アドレスの下位ビット相当
    • 幅は全体で共通で、最大データ幅から求める
  • byte_end を追加 (ペイロード)
    • バスの終端位置を示す
    • 最終フリット上の end_byte が有効
    • 幅はデータ幅から求める
  • ステータスの変更
    • ExOkay/Slave Error/Decode Error をビット単位に変更する
      • バス幅を減らす際に、ステータスは OR を取れば良い

AXI は読み出しインターリーブをサポートしているので、これをサポートする。
レスポンスパケットのペイロードに、末尾のレスポンスかどうかを示すフィールドを追加する。

1 フリットに収まらないヘッダーがある場合、tnoc_packet_packer/unpacker でヘッダーフリット扱いに不整合があり、フリットからパケットを再現できない場合がある。以下のコマンドで再現できる。

$ cd sim/router_data_width_64
$ make tnoc_router_invalid_destination_test

上記の環境場合、レスポンスヘッダーは 1 フリットに収まるが、当該モジュールでは 2 フリットで構成されている前提で処理されてしまう。
パケットの種類によって、フリット数を切り替えてやる必要がある。

AXI 用のアダプタを作る。

tvip_axi が規定外のパスにチェックアウトした場合、コンパイルできない。
sim/axi_adapter_data_width_*/local.mk にて、ファイルリストのパスが規定パスを指しているため。

noc_router を単体で使うことを考慮して、現状 localparam になっている AVAILABLE_PORTS をパラメータにする。

不正な宛先のパケットの処理を実装する。
実装するポートはローカルポートのみ。

• posted write
  • 破棄
  • レスポンスは返さない
• non-posted write
  • 破棄
  • ステータスを DECODE ERROR として、レスポンスを返す
    • リクエストが使った VC を使ってレスポンスを返す
• read
  • 破棄
  • ステータスを DECODE ERROR として、レスポンスを返す
    • リクエストが使った VC を使ってレスポンスを返す
  • リクエスト分のダミーデータを返す
    • データはコンフィグで指定する
  • バース長が 0 の場合は、データなしのレスポンスを返す
• response
  • 破棄

FLIT 幅の決め方を変える。
現在、header 全体の幅か、payload の幅の大きい方を FLIT の幅にしている。
これを、header の共通部分の幅か、payload の幅の大きい方を FLIT の幅にする。
これに伴い、FLIT 構造体 (noc_flit) に、先頭の FLIT であることを示す、head フィールドを追加する。

tnoc_router の parameter X/Y を入力ポートに変更する。

Readme などドキュメントを書く。

• 概要
• packet/flit のフォーマット
• router の詳細
  • ブロック図
  • インターフェース

The test below reprots PH_TIMEOUT error.

• Test Name: fabric_data_width_32_vc_1/tnoc_fabric_random_test
• Random Seed: 1908132033
• Simulator: VCS P-2019.06

hi taichi-ishitani ,
I'm appreciate for the Repo of tnoc. I use the vcs could regress all testcase in tnoc and view the waveform in verdi .

My question : use a 3 master to 4 slave axi port innterconnect as DUT , but i don't know how to connect the tnoc axi adapter , fabric and router as the DUT .

If the tnoc have a example of  connect the 3 parts , it's good for learner. Thank you very much!

BR,
Yuanchao

現状、Config の最大値/既定値をマクロにしておく。
Config の既定値もこのマクロを指定するようにする。

There are 3 major compilation/elaboration errors on tnoc tests with Cadence Xcelium Simulator.
Some may be Xcelium specific issues but I would like you to see the error logs:
tnoc_error_log.zip

rtl 内のディレクトリ構成を変更する。

• config ディレクトリを作成
  • 以下のファイルを配置
    • tnoc_config_pkg.sv
    • tnoc_config_defines.svh (tnoc_defines.svh から改称)
• include ディレクトリを削除
  • 中のファイルは rtl/common に移動

packet_item と flit_item の変換には flit 構造体を介して行っている。
直接変換できるようにして、パフォーマンスの改善をはかる。

AXI など読み出しデータにステータスが乗ってくるプロトコルにも対応しやすくするために、各読み出しデータにもスタータスを乗せるようにする。
ヘッダーに乗っているステータスと、読み出しデータに載っているステータスが異なる場合の挙動は、アダプターの実装依存とする。
(ヘッダーのステータスがエラーで読み出しデータのステータスがエラーでない場合、ヘッダーのステータスを優先するほうが良いかもしれない。)

burst_length のフォーマットを変更する。
現状、burst_length は、単なる、binary になっているが、PCIe のように、

• burst_length 幅
  • BURST_LENGTH_WIDTH = $clog2(MAX_BURSTS)
• burst_length = 0 の場合
  • 2**BURST_LENGTH_WIDTH を示す
• 上記以外
  • そのまま

とする。

また、現状、burst_length 幅を Config で設定するようになっているが、最大バースト長で設定するように変更する。

プロジェクト名の noc は一般的すぎるので、tnoc に変更する。

VC 1 の場合のシミュレーションを実行する。
以下の対応が必要。

• tnoc_bfm_packet_item/tnoc_bfm_transmit_packet_sequence の修正
  • packet_item と virtual_channel を紐づけている制約の削除
  • 別途、configuration で対応付けできるようにしておく
• makefile の修正
  • 特定のテストを実行しないようにする

AXI での使用を考慮し、パケットのフォーマットを変更する。

• length を廃止し、burst_size と burst_length に分ける
  • Request Header に編入する
• burst_type を Request Header に導入する
  • Fixed Burst
  • Incremental Burst
  • Wrapping Burst
• Response Header から以下のフィールドを削除する
  • Lower Address
  • Last Response

#13 の変更で、generate for を使う必要がなくなったので、削除する。

tnoc_packet.svh/tnoc_flit.svh で定義されるパラメータに TNOC_ の接頭辞をつける。

VCS 用の実行環境しかないので、 Xcelium 用の実行環境も作成する。

パケットに routing_type フィールドを追加する。
このフィールドを見て、X-Y routing をするか Y-X routing するかを決める。

ローカル側インターフェースの仕様を変更する。
現状、flit を VC 間で共有しているが、これを配列にして分離する。

• tnoc_flit_if の変更点
  • ローカルか、内部接続用のインターフェースかを識別するパラメータを追加する
  • flit を配列化し、要素数を以下のようにする
    • ローカル用の場合は、VC 分
    • 内部接続用の場合は、1
  • 他のモジュールも、この変更に合わせて、適宜変更する

特に使う予定がないので。
これに伴い、SV ディレクトリの中身を、一段上に上げる。

ユーティリティモジュールを以下のリポジトリに分離し、サブモジュールとして取り込むようにする。
