Directory not found when trying to run the flow #491

Closed GabbedT closed 2 years ago

GabbedT commented 2 years ago

Hi, i'm trying to synthetize my first custom design. I created two directories: the source files in /src/UART/ and the configuration files in /design/sky130hd/UART. I also modified the Makefile by adding the following line uncommented: DESIGN_CONFIG=./designs/sky130hd/UART/config.mk.

Then i tried to run: make DESIGN_CONFIG=./designs/sky130hd/UART/config.mk and the following output appeared:

Makefile:128: designs/sky130hd/UART/config.mk: No such file or directory
[INFO][FLOW] Using platform directory ./platforms/
Makefile:143: platforms//config.mk: No such file or directory
make: *** No rule to make target `platforms//config.mk'.  Stop.

To me it seems like that the directories aren't updated.

This is the sequence of commands i use to run OpenROAD:

 cd OpenROAD-flow-scripts

xhost +local:docker

docker \
   run \
   --tty \
   --interactive \
   --user $(id -u ${USER}):$(id -g ${USER}) \
   --net=host \
   --ipc=host \
   --env DISPLAY=${DISPLAY} \
   --volume $(pwd)/flow/platforms:/OpenROAD-flow-scripts/flow/platforms:ro \
   --volume $(pwd)/flow/scripts:/OpenROAD-flow-scripts/flow/scripts:ro \
   --volume ${HOME}:/home/${USER} \
   --volume /tmp/.X11-unix:/tmp/.X11-unix \
   --volume ${HOME}/.Xauthority:/.Xauthority \
   --security-opt seccomp=unconfined \
   --privileged \
   openroad/flow-scripts \
   bash

source setup_env.sh

cd flow

I also tried: make clean_all

I think it best that you use the OpenLane setup for your work on sky130. It is the main design script repo for this PDK. In the meantime in openroad-flow-scripts you can try running the prepackaged aes design. If that works compare your makefile to the makefile in that design directory.

maliberty commented 2 years ago

I guess you config is missing

export PLATFORM = sky130hd

but you should post it if that doesn't fix the issue.

GabbedT commented 2 years ago

@maliberty This is my config.mk file:

export DESIGN_NICKNAME = UART
export DESIGN_NAME = uart
export PLATFORM    = sky130hd

export VERILOG_FILES = export VERILOG_FILES = $(sort $(wildcard ./designs/src/$(DESIGN_NICKNAME)/*.v))                 

export SDC_FILE = ./designs/$(PLATFORM)/$(DESIGN_NICKNAME)/constraint.sdc

# Adders degrade ibex setup repair
export ADDER_MAP_FILE :=

export CORE_UTILIZATION = 70 
export CORE_ASPECT_RATIO = 1
export CORE_MARGIN = 2
export PLACE_DENSITY = 0.65

# Synthesis strategies
export ABC_AREA = 1

export FASTROUTE_TCL = $(PLATFORM_DIR)/fastroute_base.tcl

# IR drop estimation supply net name to be analyzed and supply voltage variable
# For multiple nets: PWR_NETS_VOLTAGES  = "VDD1 1.8 VDD2 1.2"
export PWR_NETS_VOLTAGES  = "VDD 1.8"
export GND_NETS_VOLTAGES  = "VSS 0.0"

@tspyrou The other designs work perfectly. Also what are the advantages of OpenLane over OpenROAD?

vvbandeira commented 2 years ago

My guess is that you generated the image before adding your design files, and the --volume parameters do not account for this use case. Can you try the following?

docker \
   run \
   --tty \
   --interactive \
   --user $(id -u ${USER}):$(id -g ${USER}) \
   --net=host \
   --ipc=host \
   --env DISPLAY=${DISPLAY} \
   --volume $(pwd)/flow:/OpenROAD-flow-scripts/flow \
   --volume ${HOME}:/home/${USER} \
   --volume /tmp/.X11-unix:/tmp/.X11-unix \
   --volume ${HOME}/.Xauthority:/.Xauthority \
   --security-opt seccomp=unconfined \
   --privileged \
   openroad/flow-scripts \
   bash

@vvbandeira Now when i run the flow:

bash-4.2$ make DESIGN_CONFIG=./designs/sky130hd/UART/config.mk
[INFO][FLOW] Using platform directory ./platforms/sky130hd
make: *** No rule to make target `export', needed by `results/sky130hd/UART/base/1_1_yosys.v'.  Stop.

I noticed that i do not have any result directory: Makefile designs objects platforms scripts test tutorials util, this is the flow directory

vvbandeira commented 2 years ago 
export VERILOG_FILES = export VERILOG_FILES = $(sort $(wildcard ./designs/src/$(DESIGN_NICKNAME)/*.v))

should probably be

export VERILOG_FILES = $(sort $(wildcard ./designs/src/$(DESIGN_NICKNAME)/*.v))
GabbedT commented 2 years ago

@vvbandeira Still got the error unfortunately

vvbandeira commented 2 years ago

@GabbedT can you fork ORFS, add/commit your changes and provide a link? Is very hard to debug make issues without access to all the relevant files.

GabbedT commented 2 years ago

vvbandeira commented 2 years ago 
export VERILOG_FILES = export VERILOG_FILES = $(sort $(wildcard ./designs/src/$(DESIGN_NICKNAME)/*.v))

should probably be

export VERILOG_FILES = $(sort $(wildcard ./designs/src/$(DESIGN_NICKNAME)/*.v))

I still see this problem here.

Also, there are a couple of commits in your fork deleting essential folders. Example: tools/ here.

Steps I ran:

The output I got looks like are issues with Yosys / your design:

GabbedT commented 2 years ago

@vvbandeira Ok, now my output is the same. When i converted the .sv files into .v the FIFO module was translated into both receiver.v and transmitter.v. Then I created another file called sync_FIFO_buffer.v and deleted the previous redefinitions. Now this is the error:

This is the updated folder: https://github.com/GabbedT/OpenROAD-flow-scripts/tree/master/flow/designs/src/UART

I searched the error but the only thing i found that is related to my problem is this: https://github.com/YosysHQ/yosys/issues/732

@tspyrou The other designs work perfectly. Also what are the advantages of OpenLane over OpenROAD?

@GabbedT OpenROAD will do floorplan to routing. The other signoff check done by OpenLane flow. Install OpenLane from here https://github.com/The-OpenROAD-Project/OpenLane Also with your UART/src file I'm able to complete the GDS generation with OpenLane with default settings. Try and let us know

GabbedT commented 2 years ago

@vijayank88 I'll try that out. Also, is it possible to visualize the synthetized design with the OpenROAD gui, i found that really helpful for synthesis exploration for the various options like visualizing heat maps, clock trees etc.

vijayank88 commented 2 years ago

@GabbedT yes you can get all features. OpenLane is an integrated platform of OpenROAD and other open source tools.

GabbedT commented 2 years ago

@vijayank88 Thanks, then i'll definitely move to OpenLane flow, can I close the issue?
