hi, please anyone tell the difference between the below if statement
1 | always @(posedge cpld_refclk) |
2 | begin
|
3 | if(!pon_rst_n) |
4 | begin
|
5 | req_rst_r <= 1; |
1 | always @(posedge cpld_refclk) |
2 | begin
|
3 | if(!v3v3_pgood) |
4 | begin
|
5 | tier_cnt <= 10'd0; |

i actually need to know the statement
1 | if(!pon_rst_n) |
and
1 | if(!v3v3_pgood) |
. if i have a pon_rst_n = 1 what will be the output and if i have a v3v3_pgood = 0 what will be the result.
