  32. PROGRAM mentor_read: Converter for .NET files
  33. @application external
  34. @text
  35. PCB netlist to ACFP converter. If a file comes from Mentor Board station
  36. use this one.
  37. @break
  38. Looks for netlists in ASCII containing tags like:
  39. @listing
  40. NET
  41. @text
  42. Invocation
  43. @listing
  44. mentor_read <net_file> [ d ]
  45. @text
  46. If a lower  
  47. case 'd' is present as the second argument, the Bison parser
  48. (interpreter of keywords and syntax) prints extremely verbose diagnostics.
  49. @break
  50. Normally the acfp file produced on standard output is redirected to a file e.g.
  51. @listing
  52. mentor_read file.net > file.acfp
  53. @text
  54. Will produce file.acfp from file.net.
  55. @break
  56. Following this it is necessary to run the output through Vertical again in order to
  57. set up properties on nets (power and ground being made not routable for instance) using the
  58. delete routable command. Alternatively the acfp file can be edited to set the net routing
  59. flags for these nets.
  60. @break
  61. There are some hints in the netlist, where attributes of some nets are given. These will appear as comments
  62. at the top of the .acfp file produced. These may help identify power and
  63. ground pins.
  64. @break
  65. If the attribute is NET_TYPE and the value following is
  66. @listing
  67. POWER
  68. SUPPLY
  69. POWERS
  70. GROUND
  71. HI-CURRENT
  72. @text
  73. Mentor_read will automatically set any nets with any attribute set to be not routable. Use set routable in Vertical
  74. to allow these nets to be routable.
  75. @break
  76. Netlist is commonly seen with a '.NET' or '.NETS' file suffix.
  77. This format comes from Mentor Graphics. It also mentions Board Station in the header of the file.
