CASE bus_rd_byte_no_i(0) IS
          WHEN BR_1_BYTE => rx_rd_ptrs_nxt(0) <= rx_rd_ptrs(0)+1 WHEN rx_rd_ptrs(0)<95 ELSE 0;
          WHEN BR_2_BYTE => rx_rd_ptrs_nxt(0) <= rx_rd_ptrs(0)+2 WHEN rx_rd_ptrs(0)<94 ELSE 1;
          WHEN BR_3_BYTE => rx_rd_ptrs_nxt(0) <= rx_rd_ptrs(0)+3 WHEN rx_rd_ptrs(0)<93 ELSE 2;
          WHEN OTHERS    => rx_rd_ptrs_nxt(0) <= rx_rd_ptrs(0)+4 WHEN rx_rd_ptrs(0)<92 ELSE 3;
        END CASE;


inthe above code I am getting errors......... SIGNAL rx_rd_ptrs : ptr_a_t;

SUBTYPE ptr_t IS unsigned(6 DOWNTO 0);
type ptr_a_t is array (pcm_channels_c-1 downto 0) of ptr_t;

I tried all combinations still geeting errors, can anyone help me.
I wanted rx_rd_ptrs_nxt should increment based on current value of rx_rd_ptrs

thanks

like I said in the dublicate thread - a case statement is a bit of procedural code and has to go in a process.
"when" is not and cannot go inside a process.

so you cannot mix the two bits of code.
