+# TGC-ISS
+
+The ISS for the cores of The Good Folk Series (TGFS) of MINRES.
+
+This ISS is based in DBT-RISE, a library to allow rapid ISS creation.
+
+## Quick start
+
+* you need to have a C++14 capable compiler, make or ninja, python, and cmake installed
+ 
+### common setup
+
+* install conan.io (see also http://docs.conan.io/en/latest/installation.html):
+  
+  ```
+
+  pip3 install --user conan==1.59
+
+  ```
+  
+  Another option is to use a Python VENV to isolate the used models from the system.
+  In case of please run:
+  
+  ```sh
+
+  python -mvenv .venv
+  source .venv/bin/activate
+  pip3 install conan==1.59
+
+  ``` 
+  
+  Using conan for the first time you need to create a profile:
+  
+  ```
+  
+  conan profile create default --detect
+  
+  ```
+  
+* checkout source from git
+
+  ```sh
+
+  git clone --recursive -b develop https://git.minres.com/TGFS/TGC-ISS.git
+
+  ``` 
+
+### Accellera SystemC build
+
+* start an out-of-source build:
+  
+  ```
+
+  cd TGC-ISS
+  cmake -S . -B build/Debug
+  cmake --build build/Debug -j10
+
+  ```
+  
+
+### Synopsys Platform Architect build
+
+Assuming environment for Platform Architect is properly set up.
+
+```
+
+  cd TGC-ISS/
+  export TGFS_INSTALL_ROOT `pwd`/install
+  export SNPS_ENABLE_MEM_ON_DEMAND_IN_GENERIC_MEM=1
+  export CC=$COWAREHOME/SLS/linux/common/bin/gcc
+  export CXX=$COWAREHOME/SLS/linux/common/bin/g++
+  cmake -S . -B build/PA -DCMAKE_BUILD_TYPE=Debug -DUSE_CWR_SYSTEMC=ON \
+    -DBUILD_SHARED_LIBS=ON -DCODEGEN=OFF -DCMAKE_INSTALL_PREFIX=${TGFS_INSTALL_ROOT}
+  cmake --build build/PA --target install -j16
+
+```
+
+Now you may change to dbt-rise-tgc/contrib to import the core model
