| 42 | Overview |
| 43 | ======== |
| 44 | |
| 45 | This repo contains a sample user project that utilizes the |
| 46 | `caravel <https://github.com/efabless/caravel.git>`__ chip user space. |
| 47 | The user project is a simple counter that showcases how to make use of |
| 48 | `caravel's <https://github.com/efabless/caravel.git>`__ user space |
| 49 | utilities like IO pads, logic analyzer probes, and wishbone port. The |
| 50 | repo also demonstrates the recommended structure for the open-mpw |
| 51 | shuttle projects. |

| 59 | =============== |
| 60 | |
| 61 | To setup caravel, run the following: |
| 62 | |
| 63 | .. code:: bash |
| 64 | |

| 75 | To update the installed caravel to the latest, run: |
| 76 | |
| 77 | .. code:: bash |
| 78 | |
| 79 | make update_caravel |
| 80 | |
| 81 | To remove caravel, run |
| 82 | |
| 83 | .. code:: bash |
| 84 | |
| 85 | make uninstall |
| 86 | |
| 87 | By default |
| 88 | `caravel-lite <https://github.com/efabless/caravel-lite.git>`__ is |
| 89 | installed. To install the full version of caravel, run this prior to |
| 90 | calling make install. |

| 97 | =================== |
| 98 | |
| 99 | Repo Integration |
| 100 | ---------------- |
| 101 | |
| 102 | Caravel files are kept separate from the user project by having caravel |
manarabdelaty | d0e7afb | 2021-04-22 00:21:13 +0200 | [diff] [blame] | 103 | as submodule. The submodule commit should point to the latest of |
| 104 | caravel/caravel-lite master. The following files should have a symbolic |
| 105 | link to `caravel's <https://github.com/efabless/caravel.git>`__ |
| 106 | corresponding files: |
Mohamed Kassem | 6f2fcd2 | 2021-04-19 10:14:19 -0700 | [diff] [blame] | 107 | |

manarabdelaty | d0e7afb | 2021-04-22 00:21:13 +0200 | [diff] [blame] | 109 | way for running openlane to harden your macros. Refer to `Hardening |
| 110 | the User Project Macro using |
| 111 | Openlane <#hardening-the-user-project-macro-using-openlane>`__. Also, |
| 112 | the makefile retains the openlane summary reports under the signoff |
| 113 | directory. |

Mohamed Kassem | 6f2fcd2 | 2021-04-19 10:14:19 -0700 | [diff] [blame] | 116 | the user wrapper: The hardened user project wrapper macro must have |
| 117 | the same pin order specified in caravel's repo. Failing to adhere to |
| 118 | the same order will fail the gds integration of the macro with |
| 119 | caravel's back-end. |
| 120 | |
manarabdelaty | d0e7afb | 2021-04-22 00:21:13 +0200 | [diff] [blame] | 121 | The symbolic links are automatically set when you run ``make install``. |
Mohamed Kassem | 6f2fcd2 | 2021-04-19 10:14:19 -0700 | [diff] [blame] | 122 | |
| 123 | Verilog Integration |
| 124 | ------------------- |
| 125 | |
| 126 | You need to create a wrapper around your macro that adheres to the |
| 127 | template at |
Manar | f088db1 | 2021-09-20 12:13:04 +0200 | [diff] [blame] | 128 | `user\_project\_wrapper <https://github.com/efabless/caravel/blob/master/verilog/rtl/__user_project_wrapper.v>`__. |
Mohamed Kassem | 6f2fcd2 | 2021-04-19 10:14:19 -0700 | [diff] [blame] | 129 | The wrapper top module must be named ``user_project_wrapper`` and must |
Manar | f088db1 | 2021-09-20 12:13:04 +0200 | [diff] [blame] | 130 | have the same input and output ports as the golden wrapper `template <https://github.com/efabless/caravel/blob/master/verilog/rtl/__user_project_wrapper.v>`__. The wrapper gives access to the |
Mohamed Kassem | 6f2fcd2 | 2021-04-19 10:14:19 -0700 | [diff] [blame] | 131 | user space utilities provided by caravel like IO ports, logic analyzer |
| 132 | probes, and wishbone bus connection to the management SoC. |
| 133 | |
| 134 | For this sample project, the user macro makes use of: |
| 135 | |
| 136 | - The IO ports for displaying the count register values on the IO pads. |
| 137 | |
| 138 | - The LA probes for supplying an optional reset and clock signals and |
| 139 | for setting an initial value for the count register. |
| 140 | |
matt venn | 4acd8b7 | 2021-04-27 11:34:42 +0200 | [diff] [blame] | 141 | - The wishbone port for reading/writing the count value through the |
Mohamed Kassem | 6f2fcd2 | 2021-04-19 10:14:19 -0700 | [diff] [blame] | 142 | management SoC. |

manarabdelaty | d8dd010 | 2021-04-30 08:40:52 +0200 | [diff] [blame] | 160 | You have two options for building the pdk: |
manarabdelaty | d0e7afb | 2021-04-22 00:21:13 +0200 | [diff] [blame] | 161 | |
manarabdelaty | d8dd010 | 2021-04-30 08:40:52 +0200 | [diff] [blame] | 162 | - Build the pdk natively. |
manarabdelaty | d0e7afb | 2021-04-22 00:21:13 +0200 | [diff] [blame] | 163 | |
manarabdelaty | d8dd010 | 2021-04-30 08:40:52 +0200 | [diff] [blame] | 164 | Make sure you have `Magic VLSI Layout Tool <http://opencircuitdesign.com/magic/index.html>`__ installed on your machine before building the pdk. |
manarabdelaty | 5f512a2 | 2021-09-20 13:20:57 +0200 | [diff] [blame] | 165 | The pdk build is tested with magic version `8.3.209`. |
manarabdelaty | d0e7afb | 2021-04-22 00:21:13 +0200 | [diff] [blame] | 166 | |

| 189 | make pdk-nonnative |
| 190 | |
| 191 | Running Full Chip Simulation |
| 192 | ============================ |
| 193 | |
| 194 | First, you will need to install the simulation environment, by |
| 195 | |
| 196 | .. code:: bash |
| 197 | |
| 198 | make simenv |
| 199 | |
| 200 | This will pull a docker image with the needed tools installed. |
| 201 | |
manarabdelaty | d0e7afb | 2021-04-22 00:21:13 +0200 | [diff] [blame] | 202 | Then, run the RTL and GL simulation by |
| 203 | |
| 204 | .. code:: bash |
| 205 | |
| 206 | export PDK_ROOT=<pdk-installation-path> |
| 207 | export CARAVEL_ROOT=$(pwd)/caravel |
| 208 | # specify simulation mode: RTL/GL |
| 209 | export SIM=RTL |
| 210 | # Run IO ports testbench, make verify-io_ports |

| 241 | 2. Flattening the user macro with the wrapper. |
manarabdelaty | fbd955f | 2021-09-20 11:59:53 +0200 | [diff] [blame] | 242 | 3. Placing multiple macros in the wrapper along with standard cells on the top level. |

| 272 | |
| 273 | You can install the precheck by running |

| 277 | # By default, this install the precheck in your home directory |
| 278 | # To change the installtion path, run "export PRECHECK_ROOT=<precheck installation path>" |

| 296 | Other Miscellaneous Targets |
| 297 | ============================ |
| 298 | |
