Description of the bug

IO error

Steps To Reproduce

pyedb/generic/process.py

 73     def solve(self):
 74         # supporting non graphical solve only
 75         if self.nongraphical:
 76             if is_linux:
 77                 exe_path = os.path.join(self.installer_path, "siwave_ng")
 78             else:
 79                 exe_path = os.path.join(self.installer_path, "siwave_ng.exe")
 80             exec_file = os.path.splitext(self._project_path)[0] + ".exec"
 81             if os.path.exists(exec_file):
 82                 with open(exec_file, "r+") as f:
 83                     content = f.readlines()
 84                     if "SetNumCpus" not in content:
 85                         f.writelines(str.format("SetNumCpus {}", str(self.nbcores)) + "\n")
 86                         f.writelines("SaveSiw")
 87                     else:
 88                         fstarts = [i for i in range(len(content)) if content[i].startswith("SetNumCpus")]
 89                         content[fstarts[0]] = str.format("SetNumCpus {}", str(self.nbcores))
 90                         f.close()
 91                         os.remove(exec_file)
 92                         f = open(exec_file, "w")
 93                         f.writelines(content)
 94             command = [exe_path]
 95             command.append(self._project_path)
 96             command.append(exec_file)
 97             command.append("-formatOutput -useSubdir")
 98             p = subprocess.Popen(" ".join(command))
 99             p.wait()

line 98 should instead be

         if os.name == "posix":
             p = subprocess.Popen(command)
         else:
             p = subprocess.Popen(" ".join(command))

This is because in linux environment you get IO error like this

Please fix wherever this issue is ASAP. I am unable to get work done as I keep having to fix edb code every time I do an upgrade.
