The initial address of the buffer of the ROM editor for a there of information from the binary file of input is entered. As the buffer is not exceeded by 64 Kb, information from the concrete file, taking into account the initial address of loading, can be a partially. The address is entered in a 16-richny format. To specify its value, it is possible to use team of numbers> the menu
For a work case with PLM chip the team loads information from the chosen file into the PLM editor's buffer, and the loaded file has to have a special text format (files of such format are created by team
and – preparation of a payment from nefolgirovanny dielectric with technological openings; – negative drawing of the scheme of conductors; in — a payment with printing conductors; 1 — the payment basis; 2 — a rezist; 3 — printing conductors of a payment.
For a choice of the file it is necessary to allocate his name, using klaviyoshi-arrows, and to press
The choice like chip of ROM or PLM is made in 2. At first the family gets out of the offered list. For this purpose keys arrows allocate the necessary name and is pressed by
The ROM editor is intended for preparation of data for ROM. The buffer of this editor is displayed on the screen after loading of the program, and further - at a choice of any chip of ROM (at a choice of a chip of PLM the PLM editor's buffer is displayed).
If at any konjyunktor one couple crossing points is not burned at least (the symbol "-" in tables, at the exit of this konjyunktor will always be 0, i.e. this konjyunktor will not influence one of output logical functions. If at a konjyunktor both crossing points for any entrance variable are burned (a symbol "x" in tables, this variable does not to influence output value of this konjyunktor, i.e. will not enter its logical function. If only one crossing point from couple is burned, the corresponding entrance changed will enter logical function of this konjyunktor in a direct or inverse look (respectively a "H" or "L" symbol in tables.
After input of necessary range of addresses for a of data from a chip of ROM, input of the initial address of a of the buffer of the ROM editor and confirmation of correctness of input of these values there is a loading of the buffer information from ROM.
Resolution of this method is higher, than at the combined positive. It is explained by a small lateral podtravlivaniye which is equal to thickness of the pitted layer and at a semi-additive method makes only 5 microns, and at combined more than 50 microns. The method provides high precision of drawing, good coupling of conductors with the basis and eliminates an unjustified consumption of copper which reaches 80% when using folgirovanny dielectrics.
On this team data from a chip of ROM are read out, compared to its control byte, after something the message that ROM "pure", or is removed the list of mistakes and the message with total results of a.
The increasing requirements to accuracy and quality of schemes, of automation of processes and growth of volumes of release of payments led to replacement of liquid photoresist with the dry film (DFF). Now as at us in the country, and dry film photoresist is abroad developed and introduced.
Data from the file of a 16-richny format are loaded into the ROM editor's buffer automatically to the necessary addresses. before such loading expediently to all addresses of the buffer of editing to write down the constant corresponding to byte, only a few from a "pure" chip of ROM of the demanded type i.e. to create a certain background. Usually names of HEX files have expansion <.hex>.
