Sigasi in Eclipse

Question

I have just installed the Sigasi Studio pluginin Eclipse (version: Eclipse IDE 2018-12). When I try to launch it,to make a new VHDL file, I get the following:

The selected wizard could not be started. org/eclipse/lsp4j/Range (occurred in com.sigasi.hdt.vhdl.ui.VhdlExecutableExtensionFactory) org/eclipse/lsp4j/Range

How I could solve it, please? Thank you in advance.

Answer 1

SIGASI + GHDL + GTKWAVE (all in one)

It is very powerful combo that you can set up. ATTENTION i use macOS 10.13.6:

Step 1

Make sure you have both installed GHDL and GTKWAVE typing

$ which gtkwave
/usr/local/bin/gtkwave
$ which ghdl
/usr/local/bin/ghdl

Step 2

Open Sigasi an make new Project and create an additional compile.sh file with:

#!/bin/sh

PROJECT_NAME="PWM_Generator"
PROJECT_NAME_TB="PWM_Generator_tb"
WORKING_DIR="/Users/imeksbank/Dropbox/UMHDL"

/usr/local/bin/ghdl -a --workdir=$WORKING_DIR/work.ghdl $WORKING_DIR/$PROJECT_NAME/$PROJECT_NAME.vhd;
/usr/local/bin/ghdl -a --workdir=$WORKING_DIR/work.ghdl $WORKING_DIR/$PROJECT_NAME/$PROJECT_NAME_TB.vhd;
/usr/local/bin/ghdl -e --workdir=$WORKING_DIR/work.ghdl $PROJECT_NAME_TB;
/usr/local/bin/ghdl -r --workdir=$WORKING_DIR/work.ghdl $PROJECT_NAME_TB --vcd=$WORKING_DIR/$PROJECT_NAME/simulation.vcd;

now, be aware, for each project you create your own variables like

• PROJECT_NAME
• PROJECT_NAME_TB
• WORKING_DIR

I use always Dropbox for such approach because then i can access via Windows as well.
And of course, there is a possibility to create custom variables in Sigasi -> External Tool Configurator -> Program -> compile_sh -> environment to pass them to make compile.sh independent. Here you have to deal with it by yourself =)

Step 3 .

Set up you External Tools Configurations to let shell script be executed by Sigasi Studio and create the .vcd file for gtkwave:

Click on currently created Project (in my case it is the PWM_Generator).
After that click on Run -> External Tools -> External Tools Configurations ....
Then go to the left sidebar and under Program create your own anchor like compile_sh.

Finally you have your route :

• Program
• --compile_sh

And now extend this anchor by a custom created shell script :

Main->Location gets ${workspace_loc:/PWM_Generator/compile.sh}
Main->Working Directory gets ${workspace_loc:/PWM_Generator}

Click Apply and Run and that's it !!! After this you can program VHDL / Verilog and compile via Run -> External Tools -> compile_sh having created .vcd. In your project appears the gtkwave file and there just double click and it starts. =)

Answer 2

Thanks to the Sigasi support, I was able to solve the problem. They wrote me:

The lsp4j plugin version is to recent for the xtext version that ships with Sigasi Studio 4.2. This issue has been resolved in the preview channel of release 4.3. Therefore - if you wish to use the plugin version of Sigasi Studio - I recommend to install the 4.3 preview following the steps explained on http://insights.sigasi.com/tech/preview.html.

That's all. Now, I would like to configure Sigasi with GHDL (as a compiler, when I run the project) and GTKWAVE (ad a waves viewer). How can I do that?

Thanks in advance.
