external 16Bit Slave, shared signals

Thanks very much for your reply,

I´m a little bit confused about the fact, that a get a signal e.g.

read_n_to_the_sram_0, write_n_to_the_sram_0, even if these signals are marked

as 'shared' in the ptf file.

You wrote:

- You need not hook up every signal that is shared (ext_ram_bus) to every pin on every chip

is it also true, that I need not hook up every 'none shared' signal to the specific chip,

if I can use a shared signal instead ?

I changed the setup of my HFCE1 chip to be_n[3..0], however it only need's two

signals be0_n and be1_n.

I did this to get a shared bus "ext_ram_bus_byteenablen[3..0].

So I will connect:

be_n_to_the sram_0[3..0] - ***not used***

chipselect_n_to_the_HFCE1_0 - HFCE1_CS_N

ext_ram_bus_address[22..0] - A[22..0] to FLASH,SRAM

and HFCE1 (A1 of bus to A0 of HFCE1, 16 Bit access)

ext_ram_bus_byteenablen[3..0] - BE[3..0] to SRAM (uses BE[3..0])

and HFCE1 (uses only BE[1..0])

ext_ram_bus_data[31..0] - D[31..0] to FLASH,SRAM,HFCE1

ext_ram_bus_readn - FLASH_OE_N, SRAM_OE_N and HFCE1_RD_N

ext_ram_bus_writen - SRAM_WE_N and HFCE1_WE_N

read_n_to_the_sram_0 - ***not used***

reset_to_the_HFCE1_0 - HFCE1_RESET

select_n_to_the_ext_flash - FLASH_CS_N

select_n_to_the_sram_0 - SRAM_CS_N

write_n_to_the_ext_flash - FLASH_WE_N

write_n_to_the_sram_0 - ***not used***

I connected "write_n_to_the_ext_flash" to FLASH_WE_N, because this signal is

marked as 'not shared' in the ptf file.

Is this correct ?
